Great results from PCM for Less tuning . . .

Huck brings up some good points. GM engineers balance power/mpg/durability/driveability/emissions carefully. Many of the PCM changes mentioned compromise durability, gas mileage and probably emissions in order to possibly eek out more power (which still needs to be proven). But we can always hope.

I am not financially connected with PCMforLess, but they shared their unprotected tuning with me. They've done a really good job. On an 06 H3 you will notice improved low end grunt and improved upper end power. Shift points are changed and believe it or not the PCM changes do NOT compromise durability, gas mileage, or emissions. Based on my experience, if you have an auto tranny the PCMforLess will INCREASE your tranny's life. Emissions do not change for closed loop (part throttle) and the net emissions decrease for wide open throttle. Most people see improvements in MPG.

The rev limiter shuts off fuel when you exceed a certain RPM. The speed limiter shuts off fuel when you exceed a certain MPH. If you don't want the speed limiter changed then don't change it.

If you put on larger diameter tires without PCM adjustments, guess what you've effectively increased the speed lmiter. The PCM will think you are going slower than you actually are.

No they don't. GM engineers tune for worst case scenario under worst case conditions for exactly the warranty period. Damn, you Cali boys really need to get outside your borders more often.

I have a couple questions. What if I get the tune, then a few months from now decide that I want to switch to 35's? Can I get an updated tune for a lower price or would I have to pay another $149?

Also, in the event that the dealer has to re-flash, is there a way to get a loaner while mine is being re-flashed with the new tune?

Sounds promising, even if it's imaginary!

But if it can be proven, that would be great.

Over 2800 posts, were they all this intelligent??



Another internet work of art. Your kind aren't worth the effort, have a good one Jr.

Let's see, I along with many others on this and other sites have posted positive things about tuning from PCM for Less. In fact, I've yet to read a negative comment from any of their customers.

Then you come along, and have done nothing but whine and bitch that "you don't have proof", actually ignoring facts that have been presented by others over the course of this thread. It would seem that the "proof" of positive feedback, far outweighs your "proof" of negativity. So here's an idea, since you want proof so bad, why don't YOU prove that it doesn't work, because it seems the tally of those whom it has worked for, far outweighs those it hasn't.

BTW, thanks for proving my point with your idiotic comments above, it saves me having to make you look stupid.

Yours truly,

The dumb Texan with his almost 700 HP Corvette!!

Sorry for the drama, didn't want your question to get lost. Kelly can answer better, but I do not believe you pay full $$ again for simple changes, but hopefully Kelly will verify.

BTW, was cruising around the internet, and found another H3 "out of the box" tune, "on sale" for $499. I won't post a link, but just another example of how good a deal PCM for Less is.

Just pay for the shipping and they'll change the program for you. It's best to hear this from Kelly though. Edit -> I was wrong about the cost; see Kelly's post below.

You have to ask them about the loaner PCM. I think they are pretty flexible and accomodating.

I just sent my PCM in for tuning. I have 35"s & a K&N air filter. I will give the board a review of the results as soon as I get it back from PCMforLess.

Whoa horsey. I don't make attacks that was just about as silly as your statements. I made my comment because it sounded like a very negative attitude like all these people are lying about their products. Nobody is going to make you buy anything to improve performance. I do know some that dynoed with positive results. 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.
