I call bs on low 15's. The power doesnt make up for the weight disadvantage. You can say it all you want but until you post a slip of your time. You ask any person that knows stuff about trucks and they'll say that low 15's cant happen on a stock 5.4

my 2000 5.4 with intake, exhaust, and vmp 93 perf only ran a 15.7.

 

i don't care if you want to believe me or not.... that's your prerogative. BTW the truck get lighter at the track.... for anyone that knows about racing knows that additional weight that can be taken off a truck is a faster time..... thanks for your all empowering comment though.

 

installed the tunes today.... all i can say is WOW.... definitely a serious improvement and would recommend tunes to anyone. The shift strategy and the fuel strategy are probably the greatest improvements of the tunes. it caught me off guard the first time i pushed the pedal to the floor. this was the 87 performance tune..... not expecting too much of a difference in the 93 perf tune.

watch out for that 2-1 down shift around 25-30 MPH its a doozy.

 

Well I have to raise the BS flag. Low 15s in a 5.4 isnt going to happen. Not stock not even close. Full bolt ons and people have problems breaking into the 15s depending on set up. My Extended cab lariat weighs in at 6000lbs. Stock it would run probably 16-17 seconds.

Also, doing a burn out does help my KDW2s stick a little more. They let me go from quarter throttle to just under half throttle launch. Do NOT go through the water box with treaded tires.

I would love to see the time slip of this low 15 run. Oh, and a 2-1 downshift wont do anything on a stock truck with just tune. It may bark the tires if the trans shift firmness is turned up way to much.


Also, anyone that has even been to the track knows that NO ONE takes the bed off the truck. Already a truck has no weight in the back at all, which is why they have a horrible time hooking up. The supension also makes it very hard for the truck to transfer weight.

You can take the seats out but you wont gain much, you sure wont gain a second unless you took out 95% of the interior.

 

Where did he say he took the bed off? I didnt see that.....

Also, why would u say that the 2-1 downshift would not be affected with tunes? That makes no sense. I didnt see anywhere that he said that it roasts the tires off from 2nd to 1st. He just said its a doozy...which could mean that it is a huge difference from stock...which I would believe....

Good to know we have yet another know it all in our presence

You know its possible to tell someone you dont believe them without being a **** about it

 

He has a fx2 reg cab short bed about 4500 lbs,1500lbs less than my crew 4x4.The old mustangs [early 90s] had 220 hp and weighed around 3500lbs and ran low 15s stock.If he can get it to launch I say he can run 15 flat.4x4 Tundras are running high 14s stock.I guess we will see if he posts timeslips.

 

where did you come up with me saying i took the bed off my truck to go to the track????? (although... my bedsides are made out of fiberglass and yours aren't)..... all i can say to that is WOW........ the only thing i said as far as loosing weight is that my track weight and daily weight changes when i go to the track........

where are you getting those facts???? jeremyGSU isn't full bolt on and he is in the 15's with i think the same truck as you.......

no one ever said anything about even barking the tires.... which BTW it doesn't do...... i was just implying that it was significantly improved about the stock 2-1 downshift.

If you are implying that a VMP 87 octane perf tune does NOTHING to the 2-1 downshift..... I will let you discuss that with Justin Starkey from VMP........ I am sure a good talk with him will change your "I know everything" ways..... you can even call up Troyer if you would like..... ohhh and bill as well. I am sure they would all be more than willing to discuss how the shift strategy improves these trucks....

you are right... when you have tires that actually respond to heat and have a softer compound rubber.... such as your KDW2s..... but when we are talking about my hard as a rock stock rubber..... its not the case... just a waste of rubber.

why are you not listening to your own advice??? BFG g-force tires have a tread and YOU said you are doing a burn out on them to get them to "stick a little more"..... just because your tread looks like COOL snake skin doesn't mean that your tread doesn't hold water like you are so lawfully enforcing to everyone else.......

truck weighs 5340 and some change on a brand new cat scale with a full tank, me(=176), Pace Edwards jackrabbit rolling cover (don't know how much these weigh), about 100lbs worth of MDF and sound equipment, about 50lbs and some change worth of steel in the bed and an entire cab lined with 2 layers of dynamat and 3 layers on the back wall and ceiling.... i will even conservatively net that at about 25 ( really closer to 40+. but just to make you happy....)

I went to the track with all of the above in/on the truck minus the steel in the bed. it ran a 15.7. the truck was launched off idle. I couldn't load the torque converter at all due to wheel spin. the below times would have been better had i had better tires so i could actually load the TC and launch properly. here is the dyno chart of my COMPLETELY stock struck on Justin's dyno at a mustang meet in orlando.... this was a benchmark dyno pull to find out exactly where the truck was at before any modding was started......



R/T... .595
60'... 2.361
330 ... 6.644
1/8... 10.151
MPH... 70.84
1000... 13.146
1/4... 15.716
mph... 87.31

that was back in october.


I will have to dig through my console and see if i can find the time slip from the last track visit.

 

I never knew that there was a character limit to posting... now i do... ANYWAYS......


On the last track visit...... was the best of 15.157. before making my way to the track on this last visit.... I took out the pace edwards jack rabbit rolling cover (i will conservatively estimate this at 50lbs....), the entire sub stage of the sound system minus wiring (at least 100lbs including entire custom box out of 3/4 MDF, 2 12" W3v3's, JL 500/1 amp, and a crappy little RF 1 farad cap to make due till i upgrade the big 3....), jack and all steel accessories (tire iron etc..) for it.... (conservatively 10lbs), full size spare tire (conservatively 40lbs....), tailgate ( conservatively 50lbs....) ohh and i lost 35lbs... but we wont go there.......soooo lets see.

that's a loss of about 250lbs.... in reality a little higher but for the sake of argument....

That puts me at a track weight of 5090lbs.

just off weight loss alone i just dropped 2.5 10ths off my previously posted time..... now with just weight loss alone we are sitting at a starting time of 15.45 or so.....

I also made a friend that works at the track... he put down a little traction compound for me since i couldn't hook up... we will say .5 of a 10th.... 15.4 now..... not to mention I am probably A LOT closer to sea level than you and most of the members on this forum (less jeremyGSU)... give me good weather, a good launch and i am having fun....

just a question IRONS1N.... what year is your truck?? ford made head changes in 2008... probably not worth much but..... you aren't a ford engineer and neither am i....

I am tired of people coming on to this forum and bashing people because they think that they know everything there is to know about everything..... People really need to learn some humility and learn that you will NEVER know EVERYTHING about ANYTHING...... no matter what the subject... you can ALWAYS learn SOMETHING new about it....

so that's enough about me running a 15.1 COMPLETELY stock.... back on topic to discussing my new VMP TUNES which this thread was started for.......

good day everyone.....

 

Nov. 7th. Yah, good weather. Supercrews are just slow. I do think if I went back to the factory 18's over the 20's I would hitting more like a 15.5ish.

I tell ya what: I would crap my pants if my screw did 16's at the track, 15's I won the lotto

FWIW- I own a 335 hp ls1 powered fbody and I would be surprised if it did low 15's...http://www.fquick.com/todbnla

 

might have to hit you up one of these days if im down in orlando on a track night or something.

 

I never said you did take the bed off, you said "weight reductions" I'm saying you cant do enough weight reductions to get into the low 15s. Unless you do something massive like take the bed off or such. Which no one does as I stated.

Full bolt ons here Runs 16.3 at best thats at 1200FT elevation for Firebird.

How is it a doozy? I know a few people with tunes on F150s. Even with a tune the "2-1" downshift isnt something to write home about.


I never said it didnt, all they do is increase line pressure in the trans to make the shifts engauge firm and quick. I have spent hours talking to Mike troyer on the phone about transmissions.

It means I bypass the water box and do a burn out after the water box. So yea DO NOT go through the water box unless on drag radials/slicks even on some drag radials I wouldnt.

 

you are in a SCREW!!!! sorry it took you all those mods and money just to reach 16.3

I have said all I am going to say about this topic.... if you have comments on the VMP tunes that this topic was started about then feel free.... if not then go elsewhere.

 

I dont run 16.3 (wasnt my truck that did it) and I dont have near full bolt ons. Other then the whipple I'm stock.

Also, VMP tuning is a VERY good company to go with, they along with PHP and Troyer are the best 3. (for sticking with the topic)

 

dude your ****ing lucky to have the only 2008 5.4 in all the US that runs a low 15 stock. and VMP does have awsome tunes, truck woke up dramatically.
