Air/Fuel Controller

Air/Fuel Controller
I have a 91 GT w/ a blower on it. I have had a burning rich problem for months now. I have did everything I could think for to regulate the fuel pressure. Nothing really seems to help I can even smell fuel in the car. I was told by a few people that I need an air and fuel controller. Does anyone know anything about this ,or maybe what would work? I am really starting to stress out about this car. Please help with any idea!!!

RE: Air/Fuel Controller
With boost your best option is to get a custom tune.
Messing with the fuel pressure just isn't going to cut it for you.
We do need more info though...
Injectors
MAF computer
other mods
A wideband O2 kit will tell you how rich or lean you are, but does not allow you to make any changes to the AFR.
A custom dyno tune or personal tuner (tweecer/pms/Moates/MegaSquirt) will allow changes to be made.

The motor is all stock but the intakes and 8psi blower,30lb injectors.255 fuel pump, 3.73, King cobra clutch, fuel regulator, 80mm C&LMAF, exhaust. Thats the most of it anyway. I have been told to get a custom chip but what if I want to add a set of heads? Then I will have to get another chip made. Where I live they want $600 to tune my car with a chip. I just dont want to spend $600 everytime I change something on my car.

its usually $600 for the tune and chip, then $200 for the retune.
you can always get an ems. there are many to choose from that range in price but you will have to tune the car yourself.
they do make an afr control that connects between the maf and the stock wiring harness although i wouldnt use that on a n/a car let alone a blown car

600 for initial,
later re-tunes are much less.
As mentioned, if you want to try tuning yourself look into tweecer and pms.
tweecer is 550, and I belive the pms is slightly more...
