HP limit?

[80superbu]

Is there any limit to how much HP the software can tune? Or how high the graphs will dispay?

Not really, more down to the injectors that the pcm can drive.
Software supports 3bar forced induction, I think delco has had some pretty beefy stuff running off the stock pcm.

there are quite a few very stout setups run from the stock pcm. best bang for the buck IMO
