Hi everyone, pretty clueless on what you can do to upgrade your prom and ecm looking for some insight. Have a 1994 chevy k1500 i put vortec heads on it, a pretty large hydraulic cam (lift 488, dur 234), and gm performance intake and it has flat tops in it. It is a complete dog right now and runs a little sparatic, I can tell its starving for fuel and air big time. Is there something I can do to send in the computer to get it programmed for these mods, or other things anyone knows of to do. I have the stock throttle body on it right now with a spacer. Thanks
