i have an 87 mustang and i dont have mass air and am running #30 injectors with a 255 lph pump. im running rich and i was wondering if i can do something to the timing or do something with my regulater since i cant take advantage of a maf and the computer doin it for me. thanx

what about it. its set at about 43psi rite now

mdvaldosta

if your running rich then lower the fuel pressure until its right

87mustang347

how will i no when its rite. and can i do n e thing to the timing to make it burn faster or no

mdvaldosta

your timing wont have anything to do with your a/f ratio. I would think that you would need a tune to with speed density to change injectors, but Im not sure.

ok so besides going down on pressure are there any programs out there i can by that will make the air/ just rite or will i just have to save up for a mass air conversion b4 i can do any thing

Sounds like you could really use the services of a good dyno shop. A good dyno shop will measure your air/fuel ratio on the computer, and will work with you to tune the car in.
Shop around in your area for one. Shouldn't cost over $100 for this. I got 3 pulls on a dyno for $50 in my area.
