No Ideas? Seems like it starts up low and idles up slowly. Has nothing on top end. Done LTFT edits at half about 4 times.

You are a little long on air in the MAF. You have a wideband so should be able to dial that in fairly close in about 3 passes.

Really need to know the issues you are seeing are exactly. Need to log MAF(Hz) to tune MAF. AFR Commanded is always blank. Do you have the right PID?

29 degrees of timing on a 150 shot? Dude... Your nuts saying the LEAST... What pulls timing for this nitrous blast? I don't see a controller listed.. Be lucky if this motor makes many passes that high....

Looking at your tune if you hit the car with any additional cylinder head pressure like NOS, turbo or SC with 26 degrees of timing and no water Meth or 105 race fuel you will cause detonation. The motor will eat itself to death. Even with that if you did not stud the heads you will lift one. All bad. When the NOS hits you have to have something pull timing or you have to run less timing all of the time. If the motor could handle the pressure maybe 10 to 15 degrees if the fuel was good.
