It just hit me that "here is somebody else that wants an education by getting people to do the research for him and still be doubtful of the results." So don't worry about it. I personally bought a PCM outright and have one programmed, end of problem.
I also have a diesel and it's a 95 Cummins and it's all mechanical to modify it. No electronic mumbo jumbo you actually have to get your hands dirty. I dynoed it at each stage and the same type of products showed positive results. But what does that have to do with a H3 I-5 except it tows mine real good on long hauls. What the heck something worked!

Fair enough, just asking a few questions, stating a few observations before I screwed with the brain on my Hummer. I didn't know there was a check valve on the dialogue. I'll just take other people's word for things now? I'm not doubting so much as asking pointed questions about what they're doing and how they're getting results that you guys are impressed with.

How much is a new brain, how much does it cost to get it programmed at the dealer should things go wrong? If the tranny pukes a week after it's installed, is Hummer going to deny the expensive claim? The reason I'm making a big deal about this is that I'm probably going to do the programming, just need a few questions answered before I hassle with it.
