[QUOTE="BurnOut, post: 1206151, member: 21501"] Reading all this and looking at the MPT dyno graph, I am both excited and trepidatious... looking at how lean they're running that 93PRX tune has me REALLY puckered. That said, I'll gladly admit that this is the first time I have really looked in-depth at the tuning of a DI motor, so maybe it's the DI that's letting them get away with it... but for comparison's sake, whereas the 93PRX dyno shows ~15:1 A/F for most of the pull, I am used to seeing 13:1-12.5:1 on [I]naturally aspirated[/I] motors... boosted motors are usually between half a point and a full point richer still. However, it seems like only a relative few have had detonation problems, and MPT has addressed those, so maybe I'm overthinking it... [/QUOTE]
