Hey guys, I googled searched for some ZZP Dyno tune reviews and experiences. Most of it was the Cobalt guys. I'm planning on taking mine there soon to get the PCM up to date and the car running more smoothly. Does anyone have any experience with their Dyno tunes? I know street tunes better, but I shot myself in the foot with Paul at PRJ for cancelling a few times due to weather, personal stuff, and new car crap that I had to deal with.
