Issue I have is that it is really quite bad at low RPM and I am getting some pre-det at 5K+ too (not much but a little) when running a tune. When running factory, it is all normal.

Just wondering if there is something that may lead to pre-det - fuel filter? Coil packs? I am not throwing any codes...

Good times...
