Okay so i have a friend who swears a modded obs will kill a lb7. The truck he wont say how much it has in the motor of the obs stroker but it kills chipped superduty 7.3s... Well i told him that if i had 2k in a lb7 i would kill a obs 7.3 with 2k in it...
the obs 7.3's were less then 230 hp stock, so you already have 70 hp on him there. I wouldnt lose any sleep over it, he probably just has duramax envy.

Most will say it takes alot more money and time to make the power with a 7.3 that a d-max can with just a few mods (EFI, Lift Pump, Trans Upgrade)

trans upgrade is gonna run more than $2k.
You can smoke 95% of the trucks out there with good tuning, and still be safe on your tranny.
