14.9 is what the 6.2 is rated at stock. granted that's without the tires, toolbox, and hitch...but thats also without the tune. and from what i have read, with tunes on stock trans, they run 13's. sounds pretty damn similar to me!

i think all the trucks are impressive IMO, especially considering they are all so damn heavy. the Ford mileage sounds I'll be looking forward to the videos!

Ive yet to see a tune only 4wd or even 2wd L92 truck run a mid 13 tune only. Either way its a fairly mute point as theyre all plenty faster than the trucks offered by the other manufacturers

you can get 13's out of tune only 6.2. mid to 13's on average? thats a stretch i believe

I am the one with the stock 6.2 and before it i had a 2003 regular cab z71 tuned and outran the f250 by about a length or so. So either ur 5.3 is sick or the f250 has a giant tune, and i still dont see that happening.

I do have a converter, and of course stock they arent much as is the case with any diesel, but throw $500 at them and they are fast as ****. And no I wasnt catching him, look at the trap speeds, he is putting down way more power than I am, even the 2000lb weight difference doesnt make up for it.

What kinda convertor are you running and who tuned your truck? If you dont mind me asking.
