WTB: an experienced technicians help

[4seasons69]

ok so I'm having a hard time getting my car running right. I have a 1990 eagle talon tsi awd. my main issue is I get a lot of knock on little amounts of boost. I've already done a lot to help suppress it I'm running 1 range colder plugs, fmic, 650cc injectors, afpr, walbro 255lph fuel pump, I always run 92 octane, and I have fixed a lot of boost leaks. I'm not sure if I still have leaks I can't find or if it's a tuning issue or what. when I put race gas in the knock dissapears then when I turn the boost up to 12psi it starts to knock again
so I'm looking for someone that has a lot of expierence with these cars preferably with some tuning experience that would be willing to help me out. and yes there will be compensation for your time. let me know if any of you are interested. thanks
