yeah 345 stock from the factory at the flywheel, I'd say around 380 at least. True you lose more from being AWD but gotta love traction that never fails you... ever. I wish my truck was AWD, you can do enough mods to where all that weight and drivetrain loss become less and less of an issue... if you go large enough. Kick ass truck either way, and I can tell just by driving it after the tune it's getting a lot more HP now.
