driveability, that's for friggin sure. I had some issues till I got a brake vacuum canister and a speed density tune. As far as the LS6 computer thing...umm....no. Essentially, it's the same as an LS1, just a different program. A good tuner will reflash your computer and tune it to how the engine should be run. I hit 500rwhp and 510 ft lbs running an LS6 with JPR S2 heads, a TR230/224 cam, full bolt on's and 11:5.1 CR. LS6 has better oiling and windage overall, that's about it.

I sacrificed huge dyno numbers for driveability and better "under the curve" motor performance. A car that makes above 350 at the wheels from 5800 to 6800 is not going to be as fast as one that does it from 4000 to 6800. Still I was tempted to slap a monster cam in there just for the hell of it after putting the heads on. Also, the dyno guy told me there was more WHP to be made if I got rid of my heavy ass 18x10.5" Chrome C6's, with 295/35's to boot. Screw that, I like my wheels, plus I need the traction.

Take a look at my dyno numbers, but REALLY take a look at the 1/8th mile performance, after all is said and done, WE DON'T RACE ON THE DYNO. Big numbers don't mean jack if you can't win races.

mine hit 396rwhp with AFR heads, long tubes,ofy, cam and Borla cat back. the guy that tuned it said get rid of those " little injectors" put a throttle body,intake and a little more tuning and easily be over 400. but like everyone has said.... hp= $ .....i figured for at the time then the cost of a divorce wasn't worth getting into the 400 club lol .....but now 3 yrs later.... sliding a few things on top now lol ....SHHHHHHH!!!!!!!

Most cam only cars with the M6 see 400RWHP these days.
