What To Add To Improve Performance

[asburydan]

My Mustang is a 2009 GT with auto trans. I put a new axle back exhaust on to improve on the stock sound, but there are no other mechanical mods. I've done a few exterior mods like gas tank Bullitt lid, chrome on taillights, etc. I have driven it about 28,000 miles since buying it with 12,000 miles August 2010, so now I have 40,100 miles. What suggestions do you have for me to make it a little quicker and stronger. I am a 70 + guy without lots to spend, but willing to look at options of which I assume cold air might be the first. Any suggestions would be helpful. Thanks very much.

I just posted a thread with the build list for my car. Through various mods I was able to go from 270 rear wheel horsepower to 330. Car feels great now, even in 4th and 5th!

Gears and tune are probably the two most cost effective ways to enjoy the car.

JLT Gen 3 cold air intake with an SCT X3 tuner, and gears. You're looking at eight to nine hundred dollars minus the cost of the gear install, if that's not something you're comfortable doing yourself.

Underdrive pulleys and axle back exhaust can be done without a tune. Not a huge gain, but it helps. Pulleys help more, but the axle back sounds good. Pretty much everything else also requires a tuner. What Jimmy says is probably the best bang for the buck if you can spend that much.

Cold Air Intake and a Tune. They make a huge improvement on the 3v cars. There are forum sponsors who can hook you up with these parts.
