I have installed the default 91 performance tune and notice a difference instantly. Shift points were a big difference in firmness. I noticed that my truck doesn't downshift on the usual hills it would before. Gas mileage seemed to be better too. Bottom end torque was better according to my "butt dyno" lol. I just wanted to post here and see if anybody else with my current mods have done any customizing to the default tune. Any feedback appreciated! Thanks!
My current mods:
BBK 85mm Throttle Body
Airaid CAI Kit
Custom exhaust- Locally built "true dual" exhaust using factory pipe ID. I installed an x-pipe with dual cherry bomb extremes and deleted the resonators and then replaced stock tips with 4in. x 18? in. rolled edge tips. Looks factory.
Suncoast Creations Ram Air Hood
I would love to install some headers and "redo" my exhaust with mandrel bent pipes and maybe some e-cutouts just to be annoying ahahhaa.
