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!
