Thread: zzp pcm pros and cons

They must have changed something cause neither one of my PCMs did that. One was back in 08 never had an issue. With that ZZP PCM, HAI, 3.4 pulley, 1.9 rockers, 3" dp, SSIC I put down 271hp/325tq.

Timeframe has plenty to do with it. Things change. If you say that you had 5 PCM's where all had the same issue you don't believe they would investigate the problem further. This way future customers wouldn't go through the same headache you did? Especially seeing as though you refered to the Missouri attorney to handle the situation.

I'm still curious as to why you continued using the same company after the issue was still there with the 2nd PCM.


And people think their engine is gonna blow due to the safely modding your car thread. Your comments in regard to ZZP scare people into believing if they use the same company for a PCM then they will have the same issues you did.

Not the way I was treated, no. The customer service was awful. The reason I had so many was because they wouldn't refund my money...so they kept sending them after I kept running into the same problem, with the DIC flashing 0.0's instead of doing the right thing and owning up to their own product and just giving my money back...and being the nice guy I am I gave them too many chances to make it right, obviously. Working in customer service everyday I like to believe that the customer IS always right, even though in today's society that mentality has been thrown out the window anymore. WHICH, is why I got the MO. Att. General involved...so I could get my money and my stock PCM back. It was a last ditch effort that worked.

I'm still curious as why this is so difficult to comprehend...I never paid a dime other than the gas it took to mail the PCM back to them and the inconvience of not having my car of course and having to bum rides off of people.

BUT...LIKE I HAVE SAID. If there are other PCM's out there for the same price, why not buy the one that has never had any issues, like the DHP? That has been out since before most of us even were old enough to drive. So even if ZZP has had one or two bad track records, which they have had PLENTY more, if you were new to the WBody world and you had both options at the same price, wouldn't you take the latter with less problems? Or maybe that just makes too much sense?
