Has anyone had to reprogram the ecu after installing a k&n filter and flow master exhaust. If so where did u get it done how much does it cost and what were the mpg and hp improvements.

 

i went Power Hungry performance for my chip, and did the extra tune for my cold air intake, i had the chip for about a year, i get 16.5 city and 22 HWY MPG's keep in mind that is driving the speed limit, as for the Tq and HP i am not quite certain but i think 22 HP and 45 Tq
