what size pully did you get and were? i have e 3.40 head unit pulley and im only seeing 4 psi and id like to see 7 psi
This was the most difficult task in my opinion, I cut the hole in the deck (Trap door) to get access to the pump. When I'm done I will make a cover for it. The fuel pump bucket had to be modified so the pump would remain in the fuel, that's the reason for the hole in the side. The Walbro pump does not have a line to pump fuel in to the bucket like the original. Had to modify the bottom so the pump would protrude far enough for the new sock. Use this, it helped me alot(URL in First post).

If you dont want a hole in your floor you can just remove the tank from under the car out the rear. You do not have to remove the rearend and it dont take very long at all. I like a clean floor that is not chopped.

Computer tuned I had my car tuned By these guys and they are the most stand up shop out there, and they do excellent work. They know ATI prochargers like no other.
I will be bringing more work their way in the future.

This is a P1SC setup with ATI's dual IC's. 6 rib set up. Sea level in FL. Saw 3psi with 4.10 pulley, 5.1psi with 3.7, and have gone to a 3.4. I have yet to test it. I have a dyno session on 2.24.08 and I will post up after that. I have a guage with memory and the tuner can log it off the vaccum too, so will be for sure #'s...

We were selling off so many parts off of my car I didn't think it would ever seen a track again. Bob
We don't use the trap door method. There isn't anything wrong with making the trap door, but it doesn't take much time to drop the fuel tank from the car. Bob
I have the P1SC system from Bob. The tune he loaded was off, but there a ton of factors, and I have learned more as I go along. It took 4 pulls with adjustments on the dyno to get it right. I just swapped cams and upped the boost, so we'll see how long it takes my guy this time.
Install is a breeze if you have any experience. Instructions are a piece of cake. My only regret is not upgrading to the D1SC when I had the chance for $200. Do it. Just pulley it down to where you want. 7 is my goal right now for longevity with the stock bottom end. Eventually I will replace it, upgrade to D1SC, and then crank it up.

D-1SC over the P-1SC. I am completely stock and do not intend to boost over 8 p.s.i.
Why should I go with the D-1SC?
Because boost is addictive, and most people started out like you only wanting 8#'s or less, but then once they had it for a while, like a hint of cocaine to an addict, they wanted more, and chances are, so will you. The D1SC is capable of the low boost like the P1SC, but then can be pullied to the much higher boost levels, and it only costs a little more than the P1SC, so it just makes since to get one now, instead of going through the hassle of doing it later.

is the D-1SC gonna be better than the P-1SC at 8 p.s.i. ?
The D1SC is bigger. It is $200. Just do it. I am dowm to .4" from the smallest size normally available pulley. I am hoping for 6-7psi. The D1SC will not have to work as hard.
It is the one regret I have in my setup so far. Get it and pulley for your goal.

Agreed. However if its just a power setting or abuse level on the stock motor, you can always pulley it down. The whole idea is with the D1SC its barely going to be trying to put out 8#'s, where as the P1SC is going to be working pretty hard. Besides the option of being able to run 15+#'s of boost later, it will be less wear on the blower with the D1SC than the P1SC.
