The Cobb AP comes with an OTS 87 tune which limits the truck to about 17lbs of boost. I run it as I have unlimited free gas through my company but I can only get 87. For me the difference is $5k-$6k+ per year easy with the amount I drive. 87 is perfectly fine to run in these with normal everyday driving. If I am towing or running the truck for performance then I run 93 and change the tune. It is a world of difference. The nice part is you can also adjust the pedal like a pedal commander which improves the response of the truck greatly, you can also mount the AP and run 6 different gauges at once to monitor everything. It is a very slick setup especially for someone else like me who is looking for versatility and likes the best of both worlds.
