Default I don't think you have a problem with your maf. at ~16lbs on an 85mm maf, you're not going to make

much airflow. This will put you out of the ideal range for you chip to see, which will cause high CFs.

Although, this is just my guess since i'm not there trying to tweak your car. Have you tried yanking a bunch of timing to see if there's any difference? Or, adding fuel?

Default Yes I did take 5 degree and make primary fuel from -10 to 0.. nothing changed with CF rate

that's why I thought it was MAF

and also.. I add more boost to 21psi and 19hold

however... I could only get 220 G/s max

Oh, i didn't read that part. I thought hitachi's read high as they died, though. Unlike the boschs
