You might have different tires (diameter in actual fact), run at different tire pressures or a different rear end...As far as I know mine has just been rechipped and has a Borlas catback system for exhaust, k and n air intake and the silicone hoses on intake, et al. The chip changes the mixture and the timing both of which tend to increase power.

I haven't tested mine on a chassis dyno but it runs with its stock rear end, 3:45?, far faster than my Ls2 at 415 hp with a 4:10 rear end for punch so mine isn't truly stock but somewhere just above that but way less than ported and relieved, cammed, etc. I lust to drive an FBI or Haibeck or LPE someday or just ride in one that's 600 hp at the crank or more. There will be some of those at the 1/2 drags in Chicago in early June and it will be fun to see their results.

I just know it's fun. let the engine tell you when to shift.....mine is just what I do when I am flat out with it and about 7,000 rpm...I think the rev limiter is 7200 or so but can't remember exact numbers. I don't have a shift light but if I ran drag strips I would.
