I'm using a Boost Button flash module in my sbec ecu. Trying to use the Boost Button T/SBEC Stage II 2.2 ATX v4 as is but having a problem with the engine starts breaking up around 3000 rpms and completely cuts out above 4000. I tried several different T/SBEC v4 and v4.1 cals and they do the same thing. It runs fine when I flash back to my stock cal. Anyone have a solution? Is there newer version I could try?
