Sounds like I will eventually require the service of PHP anyway if I want to tow or become more agressive with the truck. I'm thinking I should send it in anyway just to get it out of the way. Also, does the tire size effect how PHP programs the unit? I'm runing 305-55R-20 (Radial T/As).

I don't think the 08's have the lean running problem that 04-05's had. And, unless there's something I don't understand at all, except for the transmission shifts, Level 1 is stock. However, Level 2 is supposed to be "richer" than anything else, so PHP has been recommending you use that tune until you get a custom tune. They also recommend you try to keep your foot out of it.

Bill will include your tire size and gear ratio in your custom tunes, so give him that information when you order. This eliminates you having to use the Custom Options menu to set those two values if either of them are not stock.
