Yes i could. I have 5spd so i know that when i hit a hill at 75 and it drops to 65 then the next after the edge i can hold the same hill at 73..... That explains it all.

 

Correctly done on a 3 valve motor....yes.
On a 4.6 earlier motor ........not much.

 

Why do you say that.


I know that on the 5.4's that you see a ton more gain. But i still saw a gain in my lil 4.6L

 

i appreciate the help guys. do any of you know about changing the torque converter to help get some of the power from the 5.4 back to the rear wheels?

 

Not a clue.... When it comes to autos i look the otehr way and drive to the shop... SOrry

 

Nah , in the 05 get the troyer tunes and a cat -back system - then if you really want to step it up - go with a 4.10 rear gear..But tunes for the 05 really makes a big difference.

In the 97 air in and air out - intake and exhaust and custome tune the trans with a transgo kit. Edge and Superchips don't really offer a whole lot for the 97 unless you get head work done or convert to PI's and a PI plastic intake. The plastic PI truck intakes are good and with the heads, it's a net of about 30 hp if you add long tube headers to the mix , you'll have an easy 60 hp gainer.

 

Jbrew....

I dont have the PI heads or intake. Would that yield more power and would my edge still work with them???? What should i look for if i planed on buying these? Where to look?

 

Power , yeah , same applies for your 98 as it does for the 97.

When you purchased your edge what did it say on the box - about compatibility? With PI's , your setting it up as a 2000 or 2001 4.6 motor - I'm not sure when PI heads were standard on the 4six but your edge would have to be capitable with that production year.

 

its compatible with everything up too 03 nad i know that pi's were in the late 00's i just have been scared of soing the swap and throwing a code do to differances elsewhere on the engine

 

Then the edge will work - no prob..

Wait !! No , that's wrong!! Because your computer has set parameters and your edge is communicating with a stock 98 computer. You'll need a custom tune from Troyer.

 

thats what i thought. I was afraid of that. The more and more i dig into making my engine ahve power. the morr and more i wish i had gone with mike. I just couldn't wait the month and a half for tunes... Mybe ill just ahve to say about 5k and do a 5.4 swap and get him to write the custome tune for my 4.6 pcm to run the 5.4

 

Just a little info, i was talking to my dad about this, (I installed a cai as well), anyways, he said to read the owners manual when doing the battery thing. The manual says, and I quote,

1) Reconnect terminals

2) Turn all accessories off and start truck, let it warm up to operating temp, then let idle for at least one minute

3) Turn on AC and let idle for at least 1 minute

4)Drive the vehicle around for the idle settings to adjust, this could take up to 10 miles of driving.

That is what my manual says, I have an '07 scab with the 5.4

Hope this helps!

 

If you go by the book like that - I would make sure you follow instructions for your model year.

These computers will adjust no matter how you drive her after a reboot - it just takes longer for it to do so if you don't follow the exact procedures..

That was a good post above - obviously going by the book for your model is best..

 

Weather it will work or not i still think you should invest in troyer tunes.
You should see if built54 will sell you his 5.4 motor after he puts his new one in.That thing hauls a$$.

 

That's what a torque convertor does best when it's allow to slip, it provides more torque to the transmission. It's great from a stop, but once your up to speed your just wasting horsepower. That's what great of a lockup best of both worlds, torque down low and mpg's of a 5 speed when at speed.

In my car i'm running 4.10 gears with a 10 inch torque converter that stalls around 3500rpms and it's a blast to drive around town but not so hot on the freeway. And if it rain's she just stay's home.
