i just installed mudflaps and was wondering what you gus did to get the front to mount securely,as i'm sure you know there is nothing there when you get to the engine side of wheel well. i just put a bolt and washer through the fiber/plastic wheel well. the flaps i got are awesome,about 1/2 inch thick with a stainless ford emblem laser cut at the bottom. i got them from airhawk.ca who is great to deal with.i had a hard time finding them. my ford dealer put them an my 08 f150 stopped selling them.
allso i'm running a spartan 210 tune and really don't have any black smoke,is this normal? it will blow allot of regular looking exhaust for a second on accelaration. the youtube ones seem to blow black. but i'm not preloading just getting on it as it is winter and traction is at a premium. i just drove 700 miles so i'm sure if it was wrong i would have seen an issue by now.
