hi i got a problem. i got an 87 formula 355 with slp runnners headers and exhaust, tpis zz9 cam 24 lb injectors ported 202 stock casting heads the car runs rich cold then surges like crazy after 10 mins. i have set min air rate and tps voltage. i have tried several mass air sensors and a computer. a freind tells me it might be the stock chip not being able to handle the cam and injectors. if the problem is in the programming i would like to run accel dfi because i am not done changing my whole drivetrain/ engine combo if anyone can help i would apprecieate it. thanx

Well, I still think it is the chip. Chris
