    Running 2.5 bar mpa in 2bar SD mode

    So we have a car that is a LM7 punched to a 5.7 with a comp cam and Holley tall intake manifold with 90mm TB. Car is running a big GT40 turbo charger. When going into boost the car starts to go real rich about 10 anything over 105kpa. I have pulled so much on the VE table and pulled some from the PE table. The idle is still rich as well. Will post tune soon. Any suggestions?

    As always, you must post a tune and log to get any help. Otherwise we have to look at our crystal ball.

    You appear to trying to tune with the maf active. I have modified this tune for you to use to compare. Load your file, then open this one to compare. I suggest copying across the differances and taking another stab at it.

    Also, assuming you are running a boost referanced fuel pressure regulator your injector data is wrong. If it is a brfpr then correct the data before moving forward.
