JET or PCM for less???? Need direction.

[BuzzH3]

I'm not sure why some folks have been so adamant about dyno testing the PCMForLess tune. The real noticable seat-of-the-pants difference is in optimizing the shift points. By fixing the shift points, you are essentially putting more of the available HP & Torque to the ground. To me, it's more of how it feels than what the numbers say. There have been several members on this forum that have done the PCMForLess tune and have nothing but good things to say about it. I guess it's all in what you expect from it. It's not going to be a huge increase in power, but it will likely be a noticable one. There are dyno tests on the K&N intake system that say it produces an extra 16HP. I had one of these for a while and I noticed absolutely no increase in SOTP HP. The only thing I got was more noise. I plan on doing the PCMForLess tune sometime soon. I look at it this way. It costs less than the K&N Intake and if it at least has some noticable results, then it is well worth the price.

I would choose to learn from those who have been doing this long before we came along. Those who use/wheel the H2's, Chevy Trucks, Fords, Dodge etc.

They are not that popular among those who are "in the know". It is best to research the industry as a whole. Not everybody believes in it.

Looks like our PCM for less friends are popular here too...

interesting

Now these are guys have HP Tuners, and if they are local, will custom tune your I-5 for sooper cheap....

HummBebe's link is the first negative thread on another site that I have seen regarding PCMforLess. Some HPTuners info regarding the coloradofans.com listing of people with HPTuners - the cost to buy two credits to tune a single I5 VIN is ~$100 and the cost for six credits to do a complete year of a single type vehicle is ~$300. (The colorado/canyon and H3 are considered different vehicles as far as HPTuners goes.) My point is that the people listed with HPTuners may charge a little more to cover the additional costs for credits because they probably have licenses for colorado/canyon not the H3.

I don't think the JET chip will alter the shifts are recalibrate for different tire sizes. So I don't think JET will work for you.

It looks like you have three choices:
1) Buy HPTuners and do the tune yourself for ~$500.
2) Mail order tune - from PCMforLess, for example, for $199 + shipping
3) Contact one of the people near you with HPTuners from HummBebe's link.

Bebe, not to be confrontational, but that's just another case of one person who hasn't personally tried it saying pcm4less is crap because he heard it from other "unnamed" sources.

To date, I still haven't seen anyone who has bought the tune say anthing negative about it, have you?

You mentioned 4 wheel dyno in a previous post, what would you like to see from a dyno that would convince you one way or the other?

To me and most others here the bottom line is does it improve the driveability of the truck and make it more pleasureable and the resounding answer is yes....

[HummBebe]

Are you guys all believing that the Canyon/Colorado is the same truck?

What about gearing?
Power to weight ratios?
You can't put 35's on a C/C.

The H3's are HEAVY. C/C is a truck with a bed on it.


I'm not saying it does not change it, I'm asking how we know it is optimal?

I'd rather have a stranger with a laptop ride around with me in several different driving situations collecting data, and optimize it real life.

If you go back to that forum and do some research, there are a good number of people complaining about it.

Check it out.

Going for the PCMforless doohickey myself. Won't be shy to let y'all know if it did nothing, worsened, or, improved things. (BTW, tried to call twice about something, no big deal but, got a voice recording each time - so customer service isn't exemplary if you'd care to know.)

The way I figured was I wanted to spend some money on the truck and the choices were new air-intake, exhaust, or computer software. I didn't really need any data such as dyno because these have really been more for marketing. Have y'all looked at the K& N dyno for example? The RPM that the truck must function in inorder to see a difference is NOT REAL WORLD. So why does it seem to me that people put in new air intake system without batting an eye lid (same with exhaust) as if it should do anything to the truck especially when the OEM setup is ALREADY COLD AIR .
Anyways, what I'm saying, is sometimes decisions to "accessorize" the truck don't have to be logical. How else can you explain all the BLING??

BTW, the other software solution is...http://www.teakatoys.com/Hummer_H3_C...p/z-h3comp.htm

Sounds similar to PCMforless. I wonder if someone would consider comparing the two. Hmmm....

I'll wait patiently for your opinion, appreciate your objective approach to the mod.
