+1 dont waste your time with a d-1. p1sc or F1-R. Same for vortech S trim or YSI. (need to check the new model codes).

Eagle2000GT, are your dyno numbers from running the Procharger HO or Stage 2 kit? This winter I will be installing the Stage 2, w/ the MAFia. How do you like the MAFia? Also what injectors did your kit come with?

Actually, get a D1 instead of a P1. The P1 is leaky, noisy, and will have bad belt slip later on.

Personal experience Haven't had my P1 long but I'm swapping over to a D1 already.

I'm running the P-1SC with the stage II intercooler and 42 lb injectors. I also have a BBK 75mm TB/plenum and electric water pump. The "canned" tune didn't work out well and the first custom tune had the car running rich mid-range and a little lean at 6000 rpm. That was because I had maxed out the MAF. The MAFia fixed that problem. My Air/Fuel ratio is now good and I'm having no other problems. It has various settings so if I decide to put some crazy horsepower on the motor I will not need to buy a new MAF, just change the setting on the MAFia.

Well honestly I would buy a procharger, but unless it was a race car, I would opt for the non-self contained versions.

Noisy. Yes, and I love the sound.
Leaky. Maybe, if you over fill it.
Belt slip. Not seen this one and I've got 50,000 miles on my unit.

I agree that the D1 is a better supercharger but I just can't justify the upgrade cost to myself.
