Toyota Repair: supercharged s runner problems, exhaust flange, cental illinois

Question
I have an 01 supercharged s runner . I get a terrible raw fuel smell when I begin to push any amount of boost. It starts to detonate a little and it will not perform until around 4000 rpms It has the seventh injector in the backside of the super and when i unplug it it runs terrible. Any info would be a huge help as no one in cental illinois will even look at the truck. The super is a trd that was dealer installed when the truck was brand new.  

Answer
I would focus my attention on an injector or an air leak. Look for a leaky exhaust flange or do a vacuum leak test on your intake system. I dont have a lot of experience in superchargers or turbo systems, but I do know they run of of controlled exhaust and vacuum.
