[The Punisher]

Well , we 'specialized' in 4th Gen F-bodies and C5's, they are OBDII, but 
never did any power limiting on us. I've seen over 600 rear wheel HP 
'Streetable' LS-6's (using BIG money and LOTS of time) and they never did 
any power limiting to us. We abandoned the trailblazer tuning after running 
into probs, and then burning up the stock computer and GM not having one 
available to use for several weeks(and time is $$$).

And commenting on "hypertech". I know thats the only option for alot of 
guys, but (at least on LS-1's) Hypertech tuning SUCKS!! We examined the 
Flash after each change using a hypertech, they obviously didnt have a clue 
as to how to tune the fuel and spark tables. But using a hypertech is a good 
way to find the memory locations for stuff like the gear ratio settings, rev 
limiter, speed limiter,fan temps etc...  :)
