LS1 Tuning picks up car more than long tube header swap

[Alvin@pcmforless.com]

First run is baseline, Second is after pacesetter headers + off road y-pipe. The final (highest) run is the same as above + tuning.

What I don't understand is how people say tuning isn't worth it until you go in the engine.. In this case a simple base tune picked the car up 15rwhp and fine tweaking on the dyno got another 6 or so. I mean that is the same (and better) gain that what the longtubes+ off road Y did.

Because people are retarded. Tuning on my car made a world of difference in not only the power delivery, but the driveability of the car (because of the increased low end torque). I did a cam and longtubes and tuning picked me up a little over 10rwhp/10rwtq at the peak, and over 20rwhp/20rwtq at the very least in the entire under the curve area. That is HUGE gains for $125 and the cost of a couple of pulls in the dyno (Gomer from LS1Tech did my tuning BTW).
