Bingo! this particular unit was not their standard size but the "big maf" type that is meant really for larger turbines but can be run (with a tune) on a standard size turbine.yea everythings right. no leaks, maf is on right it just is really slow and it stutters at high rpms. the p&l website says it requires ecu tuning but will it really run this bad?
With no other parts installed that would alter the AFR, this should be correct.
