I got my car dyno tuned at 21st Century Muscle Cars. John Page (the shop owner) is very friendly, accommodating and knowledgable. Kenny K., who did the actual tuning, is extremely friendly and owns his own C6 which he modified (headers, cams, etc) and tuned himself.
I was expecting to dyno at 390 rwhp stock and gain about 5 rwhp from the tune. Instead I dyno'ed very low for an LS3 (364 rwhp) and gained 30 rwhp from the tune. Apparently my LS3 C6 is an anomaly and came from the factory pig rich (AFR for the first dyno run was below 10.0), which accounted for the low horsepower.
Most LS3's are 390 stock and gain 5 from a tune. I was about 365 and gained 30 from the tune. Either way, end result is 395 rwhp... so I shouldn't be too concerned, right? Right??
Btw, for you non car people out there, 395 rwhp means my car makes about 445 horsepower. Hell, let's just call it an even 450... :)
