It feels much more responsive on the throttle. It takes less pedal to get moving and even less while cruising to get from like 55mph to 75mph. The same throttle input taking off from a stop will now break the tires much easier through first and second.How's the new cam down low? I just bought a rcsb that has a lq9 but it is also all wheel drive I'm going to put exhaust and cam in it but undecided about the cam
I haven't done a burnout yet but I'd imagine the difference would be negligible. What really surprised me, on the hwy it's a hell of a lot quieter in the cab and the little drone I had is now completely gone! The valvetrain is much quieter too.
The Sloppy Stage II kinda rocked the truck side to side at idle. The Little Chopper really exacerbated the rocking enough so, It was almost irritating. The mail order tune had the "Idle Adaptive Spark Control" Overspeed & Underspeed settings at -13 and 13. I lowered them to -8 and 8. That stopped all that rocking and idles so dam smooth now. I'm going to bump it up to -10 and 10 to get some of the "chop" sound back with probably a little shake.
The only thing I don't like is the smell. Anytime you add more camshaft overlap you have more un-burnt fuel at idle. If you have emission testing narrow LSA cams with a lot of overlap will fail. In SC we don't have testing.
