Regulator boost referenced?
FP rising 1# per # of boost?
Base Fp set at? [Vac line off and plugged]
Wideband sensor readings logged?
Excessive exh back pressure? [Ideally, not more than 2X boost]
High EGT?
Plug readings look like?

How lean?

How is the VE maxed, like 300% or something?

Do you know the fuel pressure is good at wot?

ok i had the maf unhooked and seemed to be the culprit. All i have is a narrow band and is saying rich now when wot ,so problem solved. i have my ve tables at 99.6 which is the max i can set them at on the topend and boost areas. Still working on the tune. Any suggestions on usual, boosted ,problem areas would be much appreciated.
