I used to have the 9LB CTSC. In fact, it's now on Craig's car as a standard 5 PSI setup.
Carguy, Your rough idle is not because of the Comptech fuel system. It's more likely from the convoluted path the air has to take (under bypass) from the throttle body to the intake manifold, and the fact that the IAC cannot keep up, so the IAC "hunts" for the right idle speed. I had this issue myself. It has been discussed several times on the forums. How do you attribute this to Comptech's fuel system? Have you checked your trouble codes?
As far as where your car is running rich at high RPM, this is a unique feature of YOUR car. My 9 LB CTSC was too rich in the middle of its RPM range. This is a bit of a safety factor. Being too much too rich is bad, but Im sure you realize you dont want to run too lean at the top of your RPM range.
If you want your car "tuned", im all for it, you ought to pick up anywhere between 10-20 HP and Ft-Lbs, as the manufacturer of any particular fuel system cannot tune so close from the bench to work so perferctly on everyone's car. What we are discussing here is not a custom tuning job, but switching one type of fuel system for another, right?
I would at least have a long conversation with Shad at Comptech before attempting this. He is very protective of his supercharger, and for good reason.
The guys at FactorX really know what they are doing, and would not steer you wrong. The CTSC chip y'all are talking about does not exist yet. I know we are all excited about this technology, but it does not sound like that is what you need for your car given your stated problems and goals.
Bottom line, do your homework and know what your problem (if any) is before you simply throw more money at your car by bolting something new and slick onto it, which is the natural tendency many of us car guys have!

I believe if someone came out with an upgrade for the fuel delivery system on the CT superchargers they would have several customers.
I purchased a CT supercharger over a year ago and wasn't very impressed with how they manage the fuel. I am currently upgrading my car to the 9 PSI pulley and injectors. There is a rough idle problem once the car has warmed up and my check engine light has came on twice and is believed to be related to too much fuel at WOT. I have considered adding a complex system to take care of the entire fuel curve and would of already done so if I knew of someone in the area fully capable.
So I guess what I am trying to say is if Factor X or someone else can develop a system that works with the CT you have one customer waiting in the wings and i'll bet a bunch more.
