Car won't rev past 4500rpm!!
I'm running a EFI connection setup with a 2002 Fbody manual transmission ECM on a oldschool 383 stroker. It is running SD mode. I have gone through all the parameters / limiters to try and eliminate this cut at 4500rpm with no luck.

Ok I connected up all the transmission connectors and still the same problem. Any suggestions??

Thought I give you all an update in case anyone else has the same issue running the EFI connection setup. Turns out it is the spacing of the crank sensor. I put a .024" spacer in and the car runs a lot better. It will occasionally get an intermittent miss after 6000rpm still which hopefully means I'm close. I have never come across a crank sensor so sensitive before..... I wonder if it has something to do with the location of crank trigger wheel. When I look through the hole of the crank sensor I can see that the trigger wheel sits slightly forward compared to the centerline of the sensor hole.
