Need help trying to figure out what's not letting my motor free rev easily. cartech, base pressure of 20psi. 400cc injectors. SAFC. If I go 100% when fully warmed up, it'll climb to 4500-5000 and then studder almost like a two step, and while it's studdering it'll slowly climb to redline. It's fucking nasty. Am I too rich? I have a theory on the AFC causing this. If I remember right, my old 30lb injectors did not give me this problem. Remember, free-revving only. on street under boost i'm fine.

Sometimes if i go 100% around 2250-3000 while driving my car will also my car will seem to slow down.

Your running too rich.
The Cartech has too steep or a rising rate for those injectors.
You need to bleed of a shit load of air from the cartech to lower the rising rate... ;)

even with no load on the motor?
