I have them on and just came back from a dynojet session. I received less gain than I had hoped for; but, with the sound thrown in, I'd say I'm happy overall. Most of the small gain was under the curve. Not much gain at peak power. Maybe I would have seen more if I had already changed over to an electric fan and a 4# lower pulley. I think my truck just doesn't respond as well to modifications as some others do. My STD numbers looked pretty darn good though.LOL

Mods:

*PSP 4-way chip
*LFP 1-2#(?) upper pulley
*JDM 2# lower pulley
*Accufab throttle body
*Factory Tech valve body
*B&M trans pan
*JDM's Silver Bullet cat-back
*Anderson Ford Power-Pipe air intake kit
*JLP ram air
*160* thermostat
*Oil Breather Cap
*Denso IT-20 Spark Plugs
*Gatorback blower belt

 

$1200 for 2 hp...

 

$1,100.00 LOL.... I've got about what a full Bassani system would cost in this setup. 2 hp is just the peak increase. There was an 8 hp increase at 3500 rpms. They also made 10 ft/lbs of torque at peak and 12 ft/lbs at 3500 rpms. This alone would not make me happy; but, the sound is incredible. You've got to hear it to believe it.

 

That's a lot of cash for 2hp. At least you got a good deal on the full exhaust system and did not have to pay the full $1,700.

 

Thats about the same gain as a 2# pulley.

 

I guess some trucks respond better then others:

Is that a 309 hp baseline on a Lightning Daniel? I have seen them at the dyno place I use; but, haven't seen anybody post numbers like that here. Is that a stock Lightning with just a full exhaust added?

 

YEP!!

 

Cool! I wish they would have worked out as well for me. That's pretty impressive. How many miles were on the truck when the baseline was taken?

 

Around 20,000 give or take

 

Just checking.

 

Exactly what Vin said. heheh. I had about ~22k miles on the baseline, forget what I had when the exhaust went on, but other then miles and weather (it was hotter on the exhaust pull), no other drivetrain changes.

I own a 2000L...we've got less horsepower then you 01+ fellas.

Hey Odin's Wrath do you go to the cruise in high point on thurday nites they have up there

 

Nah, I'm a little old for cruisin', I leave that to the teens and twenty-somethings. Gotta get up at 3:00 AM for work on Friday anyway.
