re: 2009 F250?

I'm just providing my own anecdotal evidence, but I have a 2010 6.4. I did egr delete and dpf delete with 250 Spartan tuner. I have put about 70k miles on it in 5 years. Haven't had a single issue.

I'm trading it in tomorrow, and they are giving me almost the exact same I paid for it in trade-in. I'm looking at a tundra now, only because I don't haul heavy loads anymore and I do more city driving.

Now people say with it programmed you will stretch the head bolts and stuff and i disagree because a 275 tune and me behind the wheel would have definitely caused them to stretch

This made me laugh. Try jamming 62psi of boost in there, and see what happens. IIRC, I could only hit ~30 on the stock tune


Eta: It was a bad mother fricker when it ran. I could beat a ZL1 to around 80 or 85 every time on the 350 tune. Never got beat by a Mustang or Charger. Stock Vettes wouldn't pull away too fast on the interstate. I stuck with the 275 because the 310 and 350 were un-driveable normally. Never raced Pepperidge, but the only truck on the road that could hang was a H&S tuned F250.

.....and then it was broken for a few years
