Pretty good

Reviewed By josh l (Saint Petersburg, FL) Reviewed for a 2002 GMC Yukon —5/1/2010 8:34 AM

I bought this for my 02 yukon expecting better mpg and hp. I have noted a 4-5 mpg improvement for highway driving, but no improvement for stop and go/city driving. As for hp I have yet to notice a difference. I have aftermarket intake and exhaust upgrades on my truck and expected this device to make a noticeable improvement but it's just so so. I may connect a back up camera to it in order to get my money's worth out of it. The shipment of this product was also extremely delayed by the manufacturer and Auto Anything only notified me after taking my money. Bottom line decent product but high priced, crappy customer service.

Jet Performance Module Reviews

Increased performance and mileage

Reviewed By Randal M (Templeton, CA) Reviewed for a 2005 GMC Yukon —4/2/2008 6:22 AM

I recently purchased a module for my 2005 GMC Yukon with the 5.3 liter Vortex engine and noticed changes immediately. The key I found was also adding a new intake like AFE or K&N to allow greater airflow as well as a new exhaust from the CAT back. In combination I am recieving an additional 4-5 milies per gallon increase. I'm not kidding about this and can prove my findings. Please note that it's really important to modify ones the driving habits, like not giving too much gas when excellerating. Overall, the module was well worth the investment and I hope that others will follow the same path. Enjoy!
