spinning 6500rpm max. car is built for it, will a 2 bar MAP be ok? car should build 15psi roughly.

 

Yea, it will be fine, you can actually take a 2bar tune up alot higher than 15psi using the PEvsRPM tables like you would with a 1bar tune, but up to 2bar those are 0'd to let the VE tables take charge, after the 2bar MAP shows 100kpa then you can add a little enrichment via RPM if it's needed.

If anybody's using a 2bar LT1 PCM at the 100kpa limit I'd like to see a datamaster log and a .LT1 or .BIN please!!! (Just for fun)
