Jet Performance Module

2004 Silverado Performance module install

The module arrived and was packaged well and in good shape. Not as easily installed as I thought it would be. Sure it is plug and play, but the original wiring harness had a couple of ridges or raised slots that helped in the alignment of the harness into the original ECU. The male side of the module has those ridges, so aligning the module on the original ECU was easy. The femaale side of the module does not have the raised slots, so care must be taken to ensure all is aligned as it should be. View more reviews...

Great Product

I purchased this unit to get better mileage and performance out of my truck. I have dual exhaust and a CAI for performance mods. Install took a bit longer than expected, due to finding the right fuse and wire routing. I have not ran on the premium yet, which requires premium fuel. Waiting until it warms up. I have noticed an increase in power when i have it on the tow tune. I am waiting until it warms up to really see any mileage increase. Overall, it is a great product. View more reviews...
