I finished installing the new Accell DFI Thruster engine management setup. I ended up reterminating most of the ends to make a generic harness fit like it should. I will have the car towed over to the tuner today to make it run right. As part of the fuel injection computer change I updated my bypass valve to a Vortech race valve and added some Aeromotive fuel rails/regulator. According to the tuner I reached the limits of my Ford fuel rails and needed to make the change. I am hoping to see somewhere around 575-600 RWHP but more importantly a big improvement in driveability. Before I kept getting idle surge when coming off the throttle. It was really embarassing and annoying.
A side modification I had to do because of the fuel rails was the distributor. My new (1000 miles) MSD dizzy has a cap that was too large to run with the aftermarket fuel rails. I ended up having to replace it with a new Accell Small cap dual sync distributor. I am not entirely sure why the dual sync distributor is better but IIRC the tuner said that it will now be able to sequential firing instead of batch firing like the Ford EFI system. A side plus is about 1-2 MPG better fuel economy. I may be off on some of those facts buy you get the idea. I will clarify the detials with him later today.
