Thread: Are there any good shops in Mass to get mods installed?

you must re do your pcm at the same time you replace your pulley. Otherwise you will create a lean condition and have a very likely chance of blowing your motor if you do not. This condition would exist throughout the RPM band and you could not baby it or take it easy to get around this. You would have to drive without the belt on your SC if you do not do these at the same time........just thought I would warn you in advance. ZZperformance rents the pulley pullers for $30.....their pulley systems are good, but do not buy a pcm through them for the 3.4 setup.

They both need to be done at the same time to get the most benefit, and you certainly should NOT put the pulley in without the upgraded PCM. Once you put in a new intake, you will already have accessed the stock PCM, so you will at least see what it is for when you are ready for the upgrade.

And I agree with others, do NOT get the ZZP PCM. Others are better like the DHP PCM is argued as the best PCM "swap" out there, of course having a custom tune specifically for your vehicle would be the best, you will get somewhat close to that with these PCM "swaps". 3800 Performance sells the DHP PCM if memory serves me correctly. Others people like others as well, just stay away from the ZZP PCM.
