I have an 89 mustang stock 302, stock heads, typhoon upper and lower, stock tb, 24lb injectors,shorty header and 3.73 gears. My maf gave out so i bought a used c&l 76 mm with sensor calibrated for 24# injectors. I cleaned maf and let dry before installing. Car idled much better than without maf. It revs perfect when not in gear but once i ahift into gear and drive down the road and stomp the gas peddle the car will just rev like if i didnt stomp. So its loosing power.

Do i need to reset the ecu?
