5 Star Tuning Cobra Kit on 5.0L
 

I want to hear from anyone who has this kit installed and what kind of MPG they are getting. I watched the vidio and all I can say is WOW! But I am looking at the MPG on 87 octane and again, WOW. But are you getting it with the ecomomy tune? If this is all true, this kit would pay for itself over the life of the truck. I have 200 miles on mine and would buy it now, but I want hard numbers as to if its worth it with the economy tune. 2011 F150 SC 5.0L. Thanks.

Since your thread got moved.. you might try the other f150 site we also sponsor; there is a long thread on our install and customer feedback.
