Hi. I bought an 87 bridgeported fc. Its running rich right now, and it is also hesitating a little once it gets to about 6k rpms. I would like to know what I can do to tune the car to that it has the proper fuel to air mixture. Thanks for your help.

what ecu/carb are you running?

I am pretty sure its the stock ecu. Thank you.

Someone can correct me if I'm wrong, but i think that anything bigger than a large streetport should have a stand-alone ECU or at least an aftermarket Fuel Controller.



I would double check to see what you have as far as your ecu. Pull the carpet back from underneath the passenger side floor-mat area. Thats your stock ecu location.

stock ecu is untunable unless you send it to Rtek to get chipped.
