    What?? Why not?

    My own car (built LS1, H/C front mount 76GTS turbo) uses HPTuner's custom 3bar OS with real time tuning for the STOCK PCM. I run 16psi on pump gas and meth for the life of it. The VE is tuned; you put in desired AFR at points under boost and you get it.

    There are many many cars well past 900rwhp with stock late model PCMs.

    Sorry my bad, I misread the original post. I did not mean to misinform, just sleep deprived when I posted that.
