reevesmanche87 Posted March 20, 2023 Share Posted March 20, 2023 For those who have a 4.0 stroker in their builds, do any of yall run an aftermarket ECU or did you get the stock one refreshed? I'm doing a 4.0 HO swap into my 86 after I build the motor and want to know the best way to do this correctly Link to comment Share on other sites More sharing options...
