hey guys, i just got my u7192 today. I have an 06 silverado z71 with the 5.3. I installed the performance tune, but i didn't notice any kind of change. It actually acts like it's a little sluggish with the tune installed. Around 20mph i use to could squeak the tires, but now it's like its running a little fat. I also tried tunning off the TM but i didn't see any change then, i left the %reduction at shifts on though. Someone give me some ideas. Do i need to the drive the truck farther, i haven't put but maybe like 10 miles on it since i installed the tune. The tuner however did make the tranny feel alot tighter. If anyone has any ideas let me know. Thanks

Yeah,I would give it a few miles to let it learn the new fuel trims.

Thanks
