Well, I got it installed yeserday and I must say that the change is great. That truly is how the truck should run straight from the factory. Im using 87 tune with 2* timing advance and performance throttle sens. I might try the 91 tune later but who knows. My afr is 11.8 - 12.8 so im in the right zone. Tires spin now with no problem (gonna have to control that. My Michelins arent cheap).
I must say though, im not impressed with the hardware. The HDMI cord seemes to be overkill and a little too bulky for the application.
I really dont like how the cord plugs into the rear of the unit, makes mounting a little more difficult, i dontwant to put holes in my dash for the cable, and now i dont know if i will be able to mount it in the sunglasses compartment in the overhead like i thought i would.
The monitoring features are cool, but the screen is so small that it really isnt practical for dedicated guages. (thats just my opinion).
I might just unplug it and use it for tunes, trouble codes, and the occasional performance test.
Love the programming, and it went in without a problem (i did hook up a battery charger the first time though ,just to be sure).
