Message I have a 1990 TT and i just recently installed 555cc injectors and a z1 prom to run the injectors. Now the engine idles like its missing on several cylinders. Will not rev past 3K. Swapped the Z1 chip with the ashspec chip and it runs slightly better but has the same problems. What could be the problem?
