wtf horsepower/ torqe issue
ok so i just got my rims and tires last thursday and aterwards the truck still ran like a bat outta hell... and starting last night I got in the truck and it was really slow like maybe even less than stock even with all my upgrades. anybody had this issue or maybe a solution idk it almost makes me wanna drop the rims and tires every once in a while. i love how quick it use to be

Uh, the forums crystal ball is broken...what upgrades did you do? What size tires/rims?
Can't really help if we don't know what you did specifically.
Got any codes set? Is the yellow "wrench" light on the dash lit, indicating the PCM is in "limp home" mode?

ok i have put a CIA an exaust and a programmer in and nitto mud grapplers 33/12.5/18
but thats the thing it still had all the power after the tires but its just been slow the last 2 days... i was thinkin it maybe bad gas but can you have bad gas if you use 93?

well thats the problem! you have the entire CIA in the truck
lol, serious note, check the brake (parking brake notorious for sticking). is the motor running rough or you just feel slow? maybe plugs or fouled fuel filter. are there any other symptoms besides "slow"?

What engine do you have? I have a 2005 STX with the 4.6 liter V8 and the exact same thing happened to me. The engine horsepower claimed by Ford is what 235 but by the time the power gets to the rear wheels it's like 175. So adding 33 inch tires makes that 175 have to work harder. Just my 2 cents.

well it was misfiring but that quite and the misfire wasnt hurting anything and didnt set off any codes... I changed the plugs about a month ago to try and fix the misfire, prolly do need a new fuel filter
