Tuning
I have a Comptech supercharged MY 03 with a test pipe. When I put the test pipe on my car obviously tripped the check engine light. I bought a O2 simulator to take care of that problem, but haven't installed it yet. It seems that my car is running rich so I bought a VAFC 1 to try to lean it out some. I haven't installed that yet. The problem I have is can I install all of these components along with the piggy-back that hooks to the ECU from Comptech and it work? If i can this seems to be a tuning nightmare and I can't find anyone with a dyno or knowledge to tune it for me around NE Ohio. Any recommendations would be appreciated.
Thanks

You mean to say you have NOT installed the Comptech ESM yet? If not, why not? The kit needs this to work properly. You may be getting more than just the code for the test pipe. You may also be getting a code for the MAP sensor seeing boost.
ps. We have a F.I. forum. Moving this there.

Am currently running a stock comptech supercharged with after cooler. Am also new to the supercharge scene. My question is, if I want to upgrade to the 7lbs pulley, can I tuned the car (professionally done of course) AS IS, without having the VFAC or the AEM EMS? Or I must have one of them to tuned with?

It might be safe, but it's not tuned. Without some aftermarket tuning device your entire tuning method is to twist the screw on the FPR. You have a bit more control with a V-AFC but it's still a bit of a fudge.
Anything more than the stock Comptech pulley and I would want at least an E-manage.

the VAFC will definetly do the job with only 7 psi. You can't really do much tunning with the FPR so that is worthless. Put the VAFC on and the 02 simulator and go to someone with a dyno and a wideband 02 sensor.
