What the best performance upgrades to a 2007 mustang v6 auto for the money?

I already have Taylor street thunder wires, iridium plugs, Grannattelli ignition coil, single flowmaster 40 series, and a drop in K&N air filter.

 

Performance wise, I highly recommend a CAI and SCT tuner with Custom tunes from either American Muscle or Brenspeed. The custom tune really wakes up the 4.0 engines!

 

I can easily say a custom tune would be the next and best bang for your buck. Especially since you have an automatic transmission! Our custom Bama tunes will adjust the shift points, shift firmness, and shift delay of your transmission. You'll also see an increase of HP/TQ throughout the powerband and significantly better throttle response!

Check out some of the Bama Customer Tuners on our AM site. Let me know if you have any questions about our Bama tunes, too!

Forget what the advertising says...On your 4.0, a CAI & good custom tune yields 15-20 RWHP, real world, plus improved driveability, especially on automatics.

 

Before I installed my ProCharger, which I also purchased at AmericanMuscle, I had this setup. Huge difference in the car, especially with the 93 race tune. I ran it for over 25,000 miles with no issues.

 

can these bama tuners be fitted and tuned yourself?
if so how exactly do they work peeps?

 

Do they make different gears for those 4.0's rear end? not to hold a ton of power, but something to have some fun with? say, 3.73's?

 

Yes. I upgraded mine with 3.73's. Buy the Ford Racing gears. I've heard bad things about other brands.

 

Sweet..
