Problems with my vortech

[88cobraconvt]

I just installed a S trim in my mustang and my car now runs like crap. I also installed a Jacobs boost control. I got the supercharger used. The guy I bought it from said he was running about 15 lbs of boost with this set up. It also came with an Anderson power pipe. I think it might be a fuel problem. The car seems to idle fine but doesnt want to accelerate. Im going to order a new pulley set up(6-8lbs) because 15 lbs is too much for my 10.1 comp. I just want to get it running decent and Ill fine tune it when i get my new pulleys. The blower seems to be running fine itself. Need some ideas were to start. Do I need to adjust my fuel pressure regulator? Please help..
