tire size vs acceleration?

[dpmac83]

I just put 35's on my 05 250 and its a dog now, I seem to have lost a good bit of acceleration. What can i do??

yea unfortunate side affect of larger tires. try a set of 38x15.50 tire and see how bad it is. but only things you can do is go back down in size, add power upgrades, or re-gear the truck.

Well the truck looks great like it is so i dont think i will go back to stock, and i dont want to regear because most of my driving is highway. I was planning on doing the FICM tune from PHP then giving one of the many progammers a call. I think that most of my problem is trans related... IE shift points and rpm stuff. however it seems that it might be getting better, but maybe i am just getting used to it. Guess my compu-mods are closer than i expected!!
