Thread: 3800 Performance PCM

So you are telling me that ZZP is selling DHP PCMs? Crazy since I would be afraid to touch them with a 10 foot pole before this since there are so many horror stories about them.

Doh... I should have read closer. Makes 100% sense now.

Their site says:
"Developed with the average 3800 enthusiast in mind, this calibration has been designed and dynamometer tested and proven for the following vehicle modifications installed:
- 3.4” - 3.20” pulley
- Cold air induction system (brand not applicable)
- Cat-back exhaust system (brand not applicable)
- Premium fuel (91+ octane)"

So what if I plan on a 3.5" pulley, and don't have a cat-back system? I will have a PLOG, and a 3" DP. I do also have ready access to 91 Octane, but not anything higher than that currently...

Hey, I start a new job on the 24th which will put me in Cedar Rapids for a month before traveling across the country for 6 months.

My parents live in East Dubuque, so maybe some time after the Labor Day holiday, I'll make the 90 minute trek to Dubuque some evening after work and see if we can do a minor "tune" like you said, and then I'll get a free meal later at my parent's house before driving back to C.R.

I'll send you a PM some time once I get some details ironed out at the new job.
