I finaly got the out to a flash light race last night and got some more logs that I will try to post. Last time I had it out it kept running lean. I changed the fuel filter put in a adjustable FPR and changed the gas. Car also has 255bbl fuel pump and 42lb injectors and use to run fine.

Some times the car runs great, sometimes it will be going good then just fall on it's face, I did notice that when it falls on it's face the boost will not see any higher then 12psi when it should be 15-18psi. And some times it is weak the whole way down the track but still running nice?

Fuel pump? EEC? any ideas?
