I'm not speaking on behalf of LMT, but its hard to know exactly how much you can "tune out" of an engine. Is the exhaust cat back, axle back, just a muffler?

Stock 5.3 + intake, exhaust, good tune...IMO maybe around 265ish at the rear.
Stock hp was @ 285 at the motor, figure drivetrain loss and your mods i think thats where you'd end up...my estimate may be a bit high.

when I had my 03 tuned it woke quite a bit. I did the same basic mods air intake and exhaust then I swapped out the clutch fan and installed an electric piece then a corvette servo for the trans.
