Have a 91 Spirit R/T. Recently purchased +40 injectors, 3 bar map and a used FWD Performance Stage 4 Cal. Turns out there is an issue with the cal and is not getting power so it either needs to be repaired or I am considering going a different route. What are my options? Is there anyone else out there providing custom tunes for these cars? For the time being I plan on throwing the stock map and injectors in, along with the stock computer.
