My friend owns a performance shop here in toms river. I waited to get the tune until i was at 1k mi. So we dynoed the truck (yes, he has an AWD Mustang load bearing Dyno) baseline was like 308/325? after the tune it only picked up about 10hp/12tq. I wasn't impressed with the numbers but.... Driving it was the difference. Between the shift points, less torque management, advanced timing, etc. that he did really woke this truck up it's now an animal..
Now for the best part.. I traveled to New York a few weeks ago with 4 people. I set the cruise at 64mph and saw 18.1mpg there and on the way back i set it at 82mph and saw 15.6mpg. this was a 45mile stint on the garden state pkwy (very hilly/curves).
POST TUNE... same trip on the way up (running late) ran it at 82mph and saw 17.9 there. even with idling in Brooklyn's bumer to bumper traffic for hours it held 14.3, then after the ride back it was 15.1 (i have no doubt that it was running 17.9+ on the way back but i didn't reset the DIC to see what a solid mix would bring). Both pre and post tune were run using 93 octane from the same gas station, HESS. I also noticed a funny anomaly. for a while i slowed to about 76mph and watched the avg fuel economy slowly change to 17.6? I then reset the cruise for 82mph again and the mileage went back to 17.9-18.1??? i know that the cruise was leaned out a bit but i was amazed what a .2 a/f difference made in this thing. i think the 6spd gearing that the truck liked the little higher rpm, more torque at that speed? enough to overcome the small drag increase i guess?
anyway thought i'd share..
