I'm looking for a shop that can evaulate my needs and help me to decide what is a good direction to go for my car. I'm looking to keep it a daily driver, but, of course, more power is more fun.

This is what I have, As far as the power goes:
'03 350Z Auto
Vortech Supercharger @ 8 lbs (Stock)
Nismo Headers
Nismo Exhuast
Crawford Intake Plenum
Stillen Test Pipes

What happens is the car becomes running too rich, and destroys the mass air flow sensor and eventually the computer to where it barely runs, or doesn't run at all. I did some research and I was considering the following:

-Larger Injectors
-2.87" Boost Pulley
-Stand-Alone ECU (Greddy E-Manage Ultimate with Specific Wire Harness)
-Dyno Tune

I dont' know what it would take to make this thing work, but something has to be done. I've made too many a trip to nissan to get ripped off and to only put stock parts back on. Any input or suggestions would be appreciated. Thanks.
