runnin' rich,how do i lean my car out?
just like the title says, my 95 gt started running super rich after i installed gt40p heads and an e303 cam. how do i go about leaning it out some without taking it to get tuned. the local shop here, Dynospeed racing, wants something like 650-700 bucks which to me sounds outragous considering i don't even have a power added. any suggestions would be greatly appreciated. thanks guys

If you have an adjustable fuel pressure regulator, turn that down.
If not, try advancing your timing to help burn off some of that excess fuel. Just don't lean it out tooo much. Lean running motors have a very short life expectancy.

stock, 19#. i know the t4k0 computers in the 94-95 are junk and have to be tuned after engine mods. my car surges some too and will die on occasion when i first crank my car.

You essentially built a cobra, minus the intake. Didn't they come with 24# injectors? You could probably benefit from a set of 24# injectors and a MAF calibrated accordingly.
That would probably get you closer. The injectors may be too small for the computer to properly adjust to the new air flow. What is your FP set at?
