I set it up in the Lariat tonight. Some odd reason I think it fit the trim of the XLT better, but the silver paint matches the Lariat trim at least, that bugged me just on the XLT grey but was much too subordinate to ever alter and the 20% tint helped shade it darker anyways.

Well by guestimate mathematics, the richer fuel will help low end get the weight moving but should not be a full blown out race up to high rpms for the sakes of running rich? As I noted in the origin post I do not want to be any bit concerned of my trucks safety, some good economy numbers for my random elevation areas and the ability to quickly pass when need be, and of most importance the health of the transmission. What ever it takes to make it last and not suffer from 33s. This is a bit of what I will need to explain when sending for a custom file.

I recall when I ran the trans only level 1 on the old truck not a thing felt different. Later when I filled up with 93 and set the level 3 timing to 1.5 wow did it sound very beastly on the start and drove excellent. Whenever I wanted it to move fast it went, however that isn't entirely my intentions with this truck. I'm just a little too worried about screwing something up this time around I guess, but the old truck was probably just a little bit of a lemon anyways.

It doesn't run that rich, just a hair more as compared to the performance tunes. I consider it safer since you have larger diameter tires. The tune is not only designed for higher load applications on the engine parameters but the shifting as well. Having the tires puts the rest of the driveline (like the transmission) at a mechanical disadvantage so torque in low RPMs when your engine/trans will be seeing more strain is ideal to make them turn efficiently down the road. The computer can make it work with speedo correctness and such, but a light throttle is what is nice on your transmission and wallet.

I don't know that you need to be "light footed". Longshot, buddy, I'm not arguing, but why did you say that? It's my understanding that the canned tunes are completely safe for any "stock" truck (i.e., not blown, no aftermarket CAI, no long tube headers and/or no X/H pipe dual exhaust mods.

Because if you are heavy footed you are more likely to break something while using the tune. It is indirectly linked.
