Sell PCM altogether and get HP Tuners...

Depends on how far in mods you want to do with that CSC. I was running a stage 3 (no pcm) but with AFC and the car ran fine but the transmission would slip BAD because the AFC had to be turned way down to accept the 36 lb injectors but still was running pig rich.

If you got the money get a programmer (DHP or HP Tuners), if not get a CSC style PCM. You did mention stage 1, so I am not sure if you got the 36lb injectors or not but with those mods you should.

BTW I have a GP GT 01. [;)]
