Hey i'm a newbie on here and i had a question.....I recently bought a set of shorty headers, throttle body, thottle body spacer, and cold air intake for my 2007 Mustang GT/CS......how much difference will this actually make in my car? I've heard mixed answers......

 

without a tune, i think you're going to be throwing a lot of codes with the headers.

the tune is where you'll maximize potential with the parts you have.

 

you def need a tune with a cai which one did ou get

 

Most people are going to say you are wasting your time with the throttle body and spacer. I don't think I have ever seen anyone get any real gains with them unless you are blown. If anything most report having nothing but troubles with aftermarket throttle bodies. I would get rid of the throttle body and spacer and buy a good tuner instead. Then you will see some real gains in horsepower.

 

good advice ^ definitely go with a tuner such as sct xcal instead of the tb and spacer.

 

I WILL HAVE TO AGREE 100%. I WAS GOING TO GET A TB BUT DIDNT BASED ON FEEDBACK FROM MANY. I DIDNT THINK ABOUT GETTING ONE ANYMORE TILL AFTER THE SUPERCHARGER WAS INSTALLED AND TUNED. I MIGHT DO IT WHEN I GET A NEW MORE AGGRESSIVE TUNE BUT I WILL ONLY USE A GT500 T.B. WHICH IS ALSO THE SMAE ONE USED ON A V10 F-150. AT LEAST IT IS A FACTORY PART AND WE KNOW IT WONT FAIL AS THE AFTERMARKET VERSIONS.

 

You changed too many things at once.
Remove them all but one and continue to install them
until no codes are thrown.
