Been running it since 5-1-10 and the car pulls all day long.
Im all for a friendly comparison, here is a dyno of a z4si (same N52 as a 330) done on a Dyno Dynamics dyno, so its a real world number and not inflated like a dynojet.
z4 3.0si
We do a full Valvetronic tune, which is different then just adding more fuel and a sharper throttle like a PBX or others do.
