I think the first answer is the best. But however it will run. It will just only bring in enough air for 19#ers. Check your plugs and see if they are rich naturally. That may be a tell tell sign. You would know though.
Get and adjustibe fuel pressure regulator. My car was running very rich as well until I got one and then got it tuned on the dyno. If you did not have the right MAF calibration for the right injectors then the car would run like hell , not just smell rich.
The first answer was almost exactly like my answer to this question on the Corral.
Just because it smells like its running rich doesnt mean it is. When I had dumps on my car it smelled rich, but on the dyno it had a 13.4:1 A/F ratio. With tailpipes on, it was fine. Lets put it this way. If the car isnt idling up and down or he has to keep his foot on the gas and fight the idle, his MAF is fine.
