Thread: zzp PCM buy

I was looking at the zzp web site and seen the PCM. I wanted to buy it but I wasn't sure if it was just a plug n drive type or had to do the security relearn. I seen all the people who bought it were 04+ sc n I have an 03 gt. If any one got any ideas with it please share.

I believe a GM Tech II scanner or HP Tuners will be able to perform a CASE learn for you.

Great I'll keep looking into it. Thanks a lot.

And if you throw the case learn code and you don't go to the dealer to get it taken care of what happens? Bad performance?

It won't read any misfires, KR, etc (correctly).
