jlee i have a 07 gt 5spd with 3.31's only thing previous owner did other than tubular rear suspension is steeda throttle spacer and pypes muffler deleteshttp://www.allfordmustangs.com/forums/2005-2010-mustang-gt-tech/730961-steeda-udps-gas-mileage-2007-mustang-gt.html
My Steeda UDPs are really good. Smooth, quiet, no charging problems, and a little bump in highway gas mileage.
I'd throw away the TB spacer and I personally prefer Brenspeed tuning. I'd look into ordering a JLT Series 3 CAI, SCT X4, and Steeda UDPsjlee i have a 07 gt 5spd with 3.31's only thing previous owner did other than tubular rear suspension is steeda throttle spacer and pypes muffler deletes
still has factory airbox(yuk) and muffler forward exhaust im looking for more hp for this summer and already eyeing a bama tuner

it'll take you from a stock ~270 rwhp to about 295 at the wheels while helping gas mileage (if you can stay out of it) and the car run smoother.
My best mod by far has been a barton short throw shifter.
Air raid is very good on most cars, but the JLT and C&L tend to be the best on the 4.6 3v. Just steer clear of cheap CAIs and ones that don't require a tune. A quality filter is vital to your engines longevity and a quality system will have a top notch filter, large diameter tube, and good temperate control.the cai im really looking at is the airaid race
10hp is 10hpyou get what you pay for and thats not a bad thing. Its all about managing your expectations.
planning on getting the steeda all alongdon't skimp on pullies...get the steeda's and be done with it. There is a reason why they cost more and they are worth every penny, in quality and performance...
