Roto-Fab results on a stock "tuned" L99 - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

NHSS · 11-21-2009, 03:43 PM

3 weeks ago my bone stock L99 had an air/fuel ratio that dipped into the low 10's on the first dyno run. After my brother did the tune, it pulled 330 hp, 343 tq SAE with a/f approx 12.5-ish. I installed a Roto-Fab cai yesterday and figured I'd be "a little lean" and would be a good idea to retune it. Got it back on the dyno today, pulled an a/f of 15 and aborted the first run. My brother retuned it to 12.8 a/f and pulled 340 hp, 350 tq SAE. HP/TQ increase was even from bottom end on up.

First pull after Roto-Fab install, check out the a/f:

Great job! I had one installed a couple weeks ago that made 8hp/9lb.

Congrats on a solid gain! It's always great to see you guys take the time to share your results. Whether you are measuring performance with a chassis dyno or the old "butt dyno", it's great to hear!
