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

[deserth3]

Hummbebe you seemed stressed. MAybe some dancing bananas will help you relax.
ANd all the modes done to your ride have been crash worthyness tested by whom????


HoosierH3 asks a valid question. Don't know if you'll get an answer because I haven't heard of anyone trying JET's system. You may be the first. I went with the PCMforless option and have been happy with it. An increase in milage by 1 to 2 mpg. Depending on how I drive. It shifts better and that anoying lag when you start to let off the gas and have to hammer it again is gone.
In short I'm happy with what PCMforless did.

Not stressed

My mods are more like a battering ram, so crash test is not necessary. In addition, H2O Hummers has been producing this type of equipment long before Hummers even existed, (mostly on HD Fords and Chevy trucks).

My issue with these types of programs are this:

They have not been dyno tested. Essentially it is a computer alteration that is purely "edumacated" guesswork. While there are improvements, I'll admit it, they are not optimal, because there is no four wheel dyno test to back it up.

I'll wait until there is some actual dyno testing before I use this type of upgrade.

A dyno on a 2 WD Colorado does not work for me.

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....

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.
