Never mind just did a search and I think i'll stay away from GMPCM sorry for the post. I know many people ask which software to use, but these two seem to be the best choices in my opinion. However, I'm not sure which to invest in. I know I could use Tuner Pro RT for free but that would be unfair and cheap on my part. It seems many people are using Tuner Pro, but who is using GMPCM? and what are your thoughts? Has any one used it with Prominator? etc... I would like any input so I can make an informed decision thanks.

Just out of curiosity can anyone get to the www.gmpcm.com website? I haven't been able to get on there for months. Unfortunately I bought gmpcm before all this crap went down. I regret it now. Come to think of it I can't get any support for my software, I'll have to ask for my money back.:werd:

There seems to be alot of agreement with your choice.

I had no opinion on GMPCM until this week when I found his forum and started reading some posts.
I have now come to the conclusion that he is a SOB. Just another pathetic fool who uses other peoples work and then spits in there face instead of thanking them.
We shouldn't look at the bad but instead look at the good. Look at all of the productive results that have steamed from public research. One man/buisness can't do it all, especially when what we are trying to do is improve upon what GM had done.
When I said we shouldn't look at the bad but instead look at the good, I mean exactly that... don't even look at GMPCM.
