Thanks. The guys at the dyno shop are big Z-Nissan builders/tuners. They said the AFR was spot on and liked the tune. They had a 335i in a few weeks ago and said the numbers were about identical on that dyno pull with another tune, it was a flash they believed, not a piggyback setup and not GIAC either.

I really want to put DPs, FMIC, Intake and Catback on the car with Stage 2 and get crazy in the future.

I can imagine having the extra 80+rwhp and tq like your setup...must be nice.

Only thing is that makes me wonder is why I got quit a a bit less torque less than the GIAC dyno runs with 91oct when I use Shell 93oct? HP was about identical with my higher octane. Thoughts? Outside conditions and dyno differences maybe, but you would think the TQ gains would be higher and somewhat closer to their gains. Auto tranny versus the 6 speed they used possibly?
