This is my first time messing with anything like a turbo so I am a little lost. I just installed an on3 turbo on my 1990 mustang GT. Installed 255 fuel pump, 42# injectors, MAF calibrated for the injectors, super dynomax dual exhaust, 35 gap in spark plugs and will be putting in the tuning chip. I will only run 6-8 pounds of boost on it. I am lost when it comes to the air\fuel mixture and the timing. I will have to drive it about 50 miles to the dyno so I am trying to get it as close as I can. I do have a good snap-on timing light but not sure if that will accomplish what im trying to do. How will I be able to tell what I need to alter or change or what do I need? Any help would be greatly appreciated.
