I purchased this for my 2003 Envoy XL 4.2L V6 for towing mostly. I also have a K+N cold air intake. My wife and I have noticed a difference in shifting gears, lower RPM's in regular driving and towing, more power where it needs to be, but have not seen a drastic change in fuel economy. Have only had it installed now for 3 weeks. I would certainly recommend this to anyone.

I sat for a long time and read many items about getting more power and performance. I wish I didn't hold off and waist my time! This item is QUICK TO ADD, POWER, POWER, POWER! Have not seen the rise of MPG yet but I love the extra power. I didn't think it would be a big diffrence, WOW I was floored. It's a must have GET IT TODAY. Pick up a K&H air filter and hold on 3000 rpm will pull you into the seat for little cash and supper quick to put in.

I was amazed at how easy the installation was as it only took me about 15 minutes, and I am mechanic. The acceleration is better, the shift point is greater and so far, the mpg is better. I've only had the module for less than a week, but so far, I'm completely satisfied with its performance.

Pretty good. Just about what i was expecting

i installed the PCM on my 03 trailblazer 4.2L and i noticed better acceleration at about 3500rpm, but nothing really below that. there was also a distinct difference in the exhaust note throughout the entire rpm range. i have a 1" spacer kit, 265-75-16 nitto terra grappler tires, and a gibson exhaust. with all of this installed and the PCM, the acceleration feels like it did when it was stock without the spacer kit and bigger tires. i haven't noticed any real difference in MPG, but i have been driving a bit spirited recently.

I have a 2003 Chevy TB LTZ with 90,000 miles. Much more power and shifts much smoother. MPG increased too; if I could only keep my foot out of it. Only regret, not buying JETCHIP sooner.
