Default N55 PS2 DCT BEF JB4 map 7 E46 FBO - 09-22-2016, 03:30 PM

Everything seems good and running strong.

N55 DCT BEF (big turbo non-E85) Map 7 E46 FBO

Been running map 7 for a few months now and ready to start turning up the boost and connecting the fuel-it TBI (installed just not turned on)

Just looking for a review of current log and direction for getting things dialed in with more boost and fuel.

Its my understanding that I read current log and increase boost 1-2 based on rpm in map 6. Keep increasing based on log results?

Log looks pretty clean. I'd crank the boost and evaluate. May run in to misfires before you run out of fuel.

Increased boost to 22 psi max.

Car is crazy fast and feels good. Just looking for a review before I increase boost a bit more.

Honestly I can't image how the car is going to feel at 26-27 psi, as of now the car accelerates violently

I actually turned mine up to 22 for the first time this morning too. I noticed that the HPFP dips to 9 when you shift into 4th. Did you notice a shutter or smoke out of your exhaust? Everything looks good to me. You could do some minor duty bias tuning if you're consistently under boost at the same RPMs.

Looks pretty good, pulling a little timing but not bad.
