ron i had a quick question prolly another dumb one to
what is the real difference between a cortex and a flashpaq it seems as thru they both have the same tuning and same number outputs. guess what im trying to ask is with my setup how would a cortex benifit me more then the flashpaq
2007 f150 4.6 2v romeo with K&N tune.
oh a side not, any chance of a exhaust custom tune to be relased i know that would be a tune per truck thing since there is so many custom ways of doing it. just asking?
one other stupid question well two. im been reading about the underdrive pulleys and the throttle body spacers. so far i have read about 20% say the pulleys are good, but the big thing was the tbs, everyone said they rob hp and make a good paper weight i cant say nothing good or bad about either, i just wanted to get your option of them. thanks ron.
