I have a 02 GMC sierra with a 5.3 Gison dual sport exhust and a air raid intake. The truck runs a 15.6 now but it seems to shift very soft and out of the power band. It is a short bed regular cab, so I feel it should run a little quicker. is there a programer that will improve this, or will manual shifting be more effective, if so what shift rpm should i try. Also what would be the best steps to get this truck in the 14's, thank you

 

ls1 edit, long tubes, upd, nitrous....easy 14s, converter, 4.10s, even easier 13s <img border="0" alt="[Burnout]" title="" src="graemlins/burnout.gif" />

 

also, a transgo shift kit wouldn't hurt at all

 

I installed the transgo first. Resulted in hard shifts everytime. Frames shutter and all that fun stuff. Trouble was, torque management was even more noticable. Fuel is reduces during shift. I bought a Superchips programmer and now it kicks sideways into 2nd <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" /> Superchips only allows for hi test gas on stock though. Not much for options really. Rev limiter raises passed my peek power. Only changes to drivetrain is K&N and 3" muffler. Stock Y-pipe and tail pipe.

 

try shifting it at the track and i can almots guarantee it will run faster. and once you get good at shifting it bump the revlimiter once on the shift. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> i run mine out to i guess 5800 rpms but you have to get the timing down and it will hit the rev limiter at the same time it shifts. it runs prety good but i will probably have tranny probs sooner than if i was not doing this.
just my .02$

edit: and i forgot i do have a hpplll and shift firm set.
