Ok so i have a lil spare change lying around and i'm either going to buy Steeda UDP's for my Bullitt or the cold air kit for the Bullitt off of MRT-direct.com which do you guys think i should buy? Price is not a factor just performance. Also if i get a cold air kit will i have to get a tune? I have an Xcal 2, but will i need to get a new tune or will it be fine with the tune that is already on there? Thanx

 

If you already have a tuner then your fine as for which one to get idk i dont have experience with either of those intakes

 

I'd say intake also....MRT makes quality products. I believe Scott Hoag the designer of the Bullitt and Mach 1 is one of the people in charge of MRT and helps them design their products.

I doubt you'll need a tune if you get an intake, but it couldn't hurt.

 

Well the under drive pullies will do a few things for you, give you half, or less of your battery recharging ability, turn your water pump a little slower, the other bennies I can't think of right now. A good CAI will help get more air through your motor, not much, but a little, maybe 5-hp. But. a cold air intake is what I would put on if I were you. I have a set of the pullies did give away if I could find someone who wanted them. No, you won't need a tune!!!

 

intake.....no u wont need a tune thats for 05+.

 

both are a waste of cash, save up your money for worthwhile mods like cams, gears, or if you have an auto a new converter
