You have any way to datalog the car? What boost are you running? I would venture to guess that the stock turbo colt ecu can't quite control the larger injectors and compinsate for more boost. If you can datalog look at the MS for the fuel injectors and see if where you are at in the injector duty cycle. Sounds to me like either go to a 63T ecu or get some way to add some fuel in.
