I have a 96 Mustang Cobra 4.6 twin cam. Recently installed procharger 10 lb kit with 42# injectors and intercooler. I have had Procharger burn 4 chips now and none are working well. When I get to 5-5500 rpm starts cutting out. Burning really rich. Going 70 down interstate air/fuel meter bounces around from high 13's to low 15's. Anyone had same problems??? Solution ideas???
