I have a 2003 Mustang
3.8. I am not looking to hot rod it, my racing days are long past, but I'd like to pull 15-25 more horses out of her. I'd also like to improve mpg which is most important. I only average 14 for the past year.
She's got 178,000+ but everything I read is contradicted in the next post. I have CAI which I will add soon and thought of 65mm throttle body, coil pack, and dual exhaust. I do not want to have my check engine
light on constantly which is another downside I read with these mods.
Any experiences would be appreciated.
