What should i tune?
 

i Have about 700 Dollars to use on my mustang...

what should i get that will have the most drastic increase in horse power and performance.

so far im thinking of an AEM brute force air intake, and maybe some kind of chip tuner, but im still very un educated in that subject. (also will a chip tuner void my warranty?)

thanks for the help in advance.

I'm getting the C&L and predator tuner combo from bamachips. It is about 600$ and everybody says it is worth it. I don't know about warranty issues though.

if they can prove that its what caused the problem, then yes it will void it. some stealerships are tools anyway and might void it if the see you reflashed the ecu. but its a simple 10-15 min process so no worries just change it if u need to go to the dealership.
i think the cai tune combo is one of the best bang for your buck you can get. so i say go for it. i got a diablosport and a tune from doug at bama.

I just put in the c&l intake w/ a bama tune (xcal3). got the 93torque tune loaded, big difference, really wakes her up

use the search you will find a ton of information on this

Welcome, and take a little time to read some of the V6 topics and you'll get all the info you need on tuning. There is no chip.
