Does anyone know if there are any wires that need to be changed when doing a dpfi-mpfi swap and a auto-manual swap? I already have both done but the car is running extreamly lean and is very slow. the dpfi-mpfiis done right for sure ive already had other people check it over. the car will only rev to 5500-6000rpm before it cuts out or hits a rev limiter of some sort. it is driveable it just has a performance problem. i have a 89 dx hatch with a ls swap.
