Hey guys and gals new to the 4.6 liter mustang platform. Wife and I jus secured a 2000 GT and are interested in doing some up grades.

What we have done so far; new shocks and struts (Tokico HP), Cold air Intake (BBK), Stainless CAT back (MAGNAFLOW), new plugs, flush and fill cooling system.

Do we now need to look into having a tune done on it as now the idle is sticking around 1000 rpms. If so does anyone know of some one around the Hagerstown, MD - Martinsburg,WV - Winchester,VA area that can do a good job?

What besides a new mid-pipe and long tube headers and a cam would/should follow? Want to keep it naturally asperated please.
 
Welcome!

Look up in the sticky section for the mods list. It can def point you in the right direction to stay n/a. Looks like your well on your way. Most stage 1 cams are real easy swaps, some don't require spring changes. Stage 2's usually do.

The idle could be multiple things. Check your t/b and see if its stock or not. It should have an idle adjustment screw on it.

To set your idle. First unplug the negative terminal on the battery, then go press the brake pedal for 30 second (this clears the kam memory in the battery as it has a back up)Hook batt back up. then unplug the iac on the front of the plenum. Start the car. Set the idle to where it is just BARELY above where the car stalls (this may take a helper to keep the car running) Then turn the car back off one you have the set screw right (remember to try to not touch the gas at all during this) with the car off, hook the iac back up and see where the car is at. ** remember to do all of this with the car at operating temp b/c it will be a bit different idle on a cold motor.

Good luck and welcome again.
