i have a 95 chevy c1500 i have a hypertech chip in it and flowmaster exhaust with no cats k&n airfilter and throttle body. the truck ran excellent had power for days. then i decided to put a holley throttle body for more. as soon as i put the holley on ive been having problems. Now when i stomp the gas to the floor it falls on its face and starts sputtering out then catches itself and gets a burst of power i believe its not getting enough fuel for the amount of air its getting now ive tried to reset the the computer i believe it has something to do with the map sensor does anyone know anything that can help me any advice will help

 

Put the stock TB back on and see if that helps. Unless tou have alot of mods to the motor, the stock TB is fine. Also look for a pinched fuel line.
