Last week I met Justin at an undisclosed location (hint, people 'round there wear mouse ears) and he turned off the AFM/DOD and tuned the truck's ECM and TCM.
I was perfectly happy with the way the truck drove beforehand. My only gripe has been its poor mileage compared to other trucks like it. I am even more pleased with how it drives now, the shifts are more firm, happen quicker and part throttle down-shifting was adjusted to occur earlier or with less pedal travel.
The tune definitely unleashed some hidden horsepower, especially above 4,000 rpms. These 2009 XL 4x4s were the lowest rated LC9s @ 310 horsepower when the others were 315-320.
It was a pleasure meeting Justin and he was patient as I missed turns, failed to follow directions and reminisced over my glory days of drag racing!
As for the mileage, well it's still terrible but not enough time has elapsed to see for sure, most of my driving since is short and local. I'm getting 10 on this current tank of E85 which is nearly all city driving.
Now, where to display the sticker? On the lower left rear glass or under the 3rd brake light? One daughter commandeered a sticker for her notebook and I'm sure the other would do the same once she notices what her sister did.
