Just installe the 14b on the d16 and it runs pretty strong but after a while of driving the car starts to bog down a little before boost pulls. Idle is sticking at 1.5-2k and Im throwing some ces. Could this be the fact that Im running 8 psi on just 255 pump and 12-1 FMU? Would it help if I get the missing link or do the 4 valve thing? Thanx
