Hey guys so i have jb4 and wanted 2 step, so i ordered the 2 step relay wired everything in and boom making music with gunshot backfires with 2 step everything worked fine....

then i removed jb4 when i was having no start issues got the car all fixed and running put jb4 back everything works fine running map 5 but 2 step wont work just revs to redline...checked power wires to the relay and the DME and made sure they were getting power you can even hear the relay and dme click over when recieving power made sure all connections and wires were tight.

im stumped why would 2 step work before but now nothing?
