HP gains

[QIK KAT]

What kind of hp gains will i see from long tubes , cats & dyno tune that i'm getting next week?

[Mark #2]

Not much unless you up the boost too, you will loose boost with long tubes and cats. Maybe 20 hp and 30 tq gain, unless your current tune is way off.

It's got a 4# lower and terry reflashed a 4yr old blue chip, right know i'm running 12# boost, which is all i really want.

You'll probably loose 1 to 2 lbs of boost so you could up to a 6 lb without a lot of risk IMHO.

I went to the 6# after the long tube Headers. Not sure about the HP the headers made....sounds nice thought :rolleyes:

Rob gained 25 hp and 25 ft lbs torwue going to longtubes with his KB. Most mortals will see 10-15 all the way.

I saw a huge difference when I put the long tubes on, of course this was on the driver seat "dyno". can't wait to see what numbers I'm making after switching to a 2.8 upper and the full exhaust. :D
