My Gibson headers should be in any day now and Im curious about the power gains. Truckperformance.com claims 15-20hp and 26lb.tq. At the gibson site the numbers are close to the same(a little higher). Can I realy expect these kind of gains? Or are there claims for sales?

 

Maybe 5 to 7hp at high rpms.

 

I put on some JBAs and well......... don't get your hopes up a seat of the pants change.... The predator that was unexpected, was like a completly different engine have it loaded.

 

I think that you'll see a little bit better return than average with the shorties since you have head work done, but I'm still guessing 5-10 at the most.

 

Scream, so when are we going to meet up at the track? Ive got some new goodies I need to try out as soon as I get them on. Between the new intake, cutouts and 3000 stall Im being optimistic on running 14 flat. O-yea, the headers to. Im going to try and put the truck on a rack and do it all at once, and see how big the total difference feels.
