    If your injectors are the mototron/deka 60's that get supplied with some superchargers then do yourself a favour... throw them away and get some decent injectors. I've personally seen flow...

    I agree with joecar... it's tripping out on one of your sanity tables.

    Can you post your tune file and a log with it going into limp mode?

    The only reason you peg the MAF is that the PCM has a 512g/s limit... the sensor itself will read higher, so you can run right up to the 512g/s limit safely. Elevation changes can catch you out, so...
