Upgrade Help

[E_VilleStang23]

I own a 2003 Mustang GT Convertible with an auto trans. The only performance upgrade is Flowmaster 40 Series 2 Chamber exhaust. I am about to purchase a BBK Cold Air Intake, FRPP 4.10 Gears, and a MAC Prochamber midpipe. I was wondering if there are any other parts I will need to make sure all of these upgrades go and run smoothly. Time is a slight issue because I want everything to be ready by the time the Hotrod Power Tour hits my city on June 6. The only thing I've heard of is MIL Eliminators for the exhaust but will I need anything for the gears or anything else for the exhaust? Is a tune absolutely necessary? (I'm not sure I have that kind of cash right now).....Any input would be appreciated thanks in advance!

You don't need anything special for your upgrades, and you should buy the mil eliminators.....If i am not mistaken, you will need to get your computer recalled for the rear gears for you speedo.......but, if you follow another car and get a rough idea of where your speedo is at 30mph, you should be fine.....

Ok so what do I need to get the computer recalled for the speedo? Is that where a tuner comes into play?

You will need a speed cal

That Speed Cal says it only fits 94-98 Autos....I have an 03 Auto.

You are very right man, my bad. I thought for sure it would work with an auto........You are going to have to go with something like this: http://www.americanmuscle.com/diablo...-mustangs.html

Everybody hit it on the head, sounds like everything should go smoothly with those bolt-ons

U will need to get the car dyno tuned chances are with those mods probally running lean as for the gears you need to recalibrate.I would suggest you get the Xcal 2 and dyno tune and yes this will cost money but it would be the best thing you could do........
