i have a 2.77 pulley a predator, and am about to buy the 4 piece BF idlers. My father is freaking out because he read somewhere that " for puts a special UV mark on the blower and stock pulley that they can see if they think that an aftermarket pulley has been installed. Also the guy said that, the Ford GT the lightning and the Cobra all have a "black box" that tell how many times the computer has been accessed." My car warranty started on 4/28/04 so now he is telling me not to mod the car until after the warranty. I looked up some information on voided warrantys, here, on this forum, but found nothing about the "black box or UV paint" Give me some advise, so far no head tick, and only warranty work was front door speaker install.
Thanks
Mark
