Every GMPP crate engine OS I've found so far has been older, and has the 512 g/sec MAF limit and 63 lb/hr injector limit. I know the E67's in the newer cars no longer have those limits...I've got a 2010 ZR1 E67 calibration that's got the same 4000 g/sec and 127 lb/hr limits that my 2010 Camaro SS E38 has. I'm just curious if the newest GMPP controllers have the new higher limits too.
