I put it on and it didn't work right And pulling it off was a pain I cracked it Which really sucked so I sent. It back to jet to see if it's jacked up on the inside if the PCM was messed up hopefully it's the programming on th PCM that's not right. Because I want to see what this thing can do dammit. Sucks when open it theirs no returning it

Installation is in a confined area on my truck. Not sure if there is any thing or not but a week later my transmission cooked/ grenade itself while I was just crusing down the road at 75 mph. So now I have to put a transmission in my truck going to be about a week of staying after work and remove and installing a $1,600 transmission. Btw glad right now I work for a towing and automotive repair shop.

After following directions(to the letter)I started the truck and the C,E.L. went out and the engine sounded fine. Then,I installed the new exhaust system(Magnaflow Catback)and,K&N cold air intake. Now,the engine runs rough(no power),sounds like ignition leads were crossed(firing on the wrong cylinders). I don't know what to try ,next. I guess I will have to take it to a garage I know and trust. Any suggestions would be welcome.

The chip didn't do as much as I expected. I noticed a little increase in acceleration. It didn't get rid of the bog when accelerating in reverse after being in drive.

I purchased the stage II performance module for my '04 Colorado, with a current odometer reading at 70,000. I have just the K&N stock replacement air filter, Magnaflow exhaust muffler, and running on 91 octane. I noticed an immediate increase in HP, mainly acceleration. I did not notice a big difference in MPG, though I believe there was an increase. I achieved 24.2 MPG highway running 75MPH constant. Was hoping for better mileage increase, but am satisfied with the extra boost in power!

HP obviously has increased as well as smoother shifting. Not sure about MPG yet, but will assume with the small advance in HP, MPG should be slightly better. I'm disappointed the unit went on sale and had a $20 mail in rebate after my purchase, but I'm still happy with the price. This is the first (real)PCM I've seen for the Hummer H3. Great service and prompt shipping.
