Best way to improve performance
 

For under 2 grand, what's the best way to get more power out of the six banger? An option I might explore is a CAI/Tuner, but what else is there?

ditch the stock muffler...

while it won't add HP a new set of rear gears will give you an extra kick off the line... might as well throw a LSD in there while you're at it...

T-lok? What about underdrive pulleys? I'm totally clueless when it comes to gears and pulleys and stuff. What do I need to look for?

I've got Magnaflow Catback dual-exit System on it already

LSD?? What is that?

Limited Slip Differential :doh:

Go with the tune and CAI, best bang for your buck.
Then I would change the gears out and go with a LSD for more get up and go.
Under Drive pulleys is a good add on.
Thought about Nitrous?

dont worry about the udp's its like 5 hp or something
Intake/ tune, exhuast( there no performance gain in duals vs single when mine was s/c i had stock exhaust switched to duals went back got dynoed and 0/0 gain...), and LSDw/ your choice of gears( im an auto and went with 3.73's), thats the most common performance mods a new car will get....

Nitrous-- when the car gets back my zex kit will be removed im gonna be selling it for pretty cheap .. everything i have now is valued over $900 for it... and your in houston im only 3 hrs away so shipping is saved.. cost pm me about it ....
also have you checked out the mustangcollective.com all v6 tuners

T-lok
 

For the life of me I can`t understand why Ford isn`t putting a T-LOK on the V6. :doh: I really enjoy the added traction and getting through the winter was priceless. As a factory option it would be plus or minus $200 but still worth having at $600 to $700 installed aftermarket.
