99% sure i'm going with the KB 2.1L intercooled kit... how much boost would you run on a stock motor? IK it depends alot on the tune but just trying 2 get a rough idea. ik people say 8lbs is as high as you should go stock but could i get away with 10lbs with a good tune?.

8-10lbs is is high as I would go on a stock bottom end. Your tune is the most important when you start throwing power adders in the equation though so make sure you trust your tuner or you go with a trusted tuner. You will love this setup.

I have a 14lb pully and it makes 15lbs. yeah always expect a +or - a 1to2 lb range. It all depends on the setup of the motor.

yah i'm leaning towards 9-10lbs...i get a "free" dyno run be-4 the blower and a dyno run and tune after the fact with them doing the install...i might just go 9lbs and then take it to mustang magic and have them tune it for 10lbs down the road..ik that 8 or 9lbs will keep me smiling for a few weeks.:D

In that case stay with what everyone suggested 8 - 10

8 psi maximum intercooled boost recommended for stock 2001-04 4.6 2V GT’s

The reason I bought a 99 GT and put the Procharger on it a couple of years ago is because the 99 motor is a little stronger and even SC companys mention it if you read between the lines

99-01 model years with over 10 psi boost require Ford Lightning MAF, Ford part #XL32-12B579-AA (not supplied)

I bought a lightning maf off corral.net a few years back for 100 bucks. I would look around and cut the tubing as well. Alot cheaper. I bought the kit threw KB and its a pile of plastic. Not worth the money to me but gets the job done.
