i was looking through something and this modified pcm for 3800performance.com caught my attention..any one with the 411 on this this or is it junk?

 

it depends on what your are looking to do but I would say a modified pcm is a great investment. If you plan on modding your car it is a must. Definately worth the money especially if your car is throwing a cat code.

 

I question it being worth $100+ if you'r throwing a cat code (P0420) for having a high flow cat. I did some research and a lot of people (all makes) who have put high flow cats on have defeated that code by modding a couple of spark plug non/anti-foulers from the parts store (less then $10). When I did my high flow cat, I was prepared to do that if I got that P0420 code.....

BUT, I modded my Monte heavy enough that I HAD to get a PCM tuned and had that code deleted at the same time. I worked with PCMforLess.com. Service was great and the PCM is working AWESOME!

 

I highly recommend a tunned PCM for extra performance. In the case of the tuned PCM for my 3.5L, it also did WONDERS for the transmission, which is the same 4T65-E that all of the later model Monte Carlo's use.

 

There are a few companies that can do this for you.

Just try to do this LAST in your modification lists (unless you are top-swapping and can't run the car without it, obviously you'll need to do that at the same time)

well im not really doing any crazy mods i wish i had the money for that, just looking for some trapped hp here and there lol thanks fellas
