Isx cm 870

Whoever did your demandate is a moron. 870's have derate logic located in the ram memory that can't be accessed in the program itself, it must be edited live. If this person doesn't even know that about this engine then you can bet your ass the rest of that program is garbage too.

Tell him you want your money back and have him flash it back to stock, then unplug the EGR temp sensor (won't hurt it a bit) and drive it like that. It will derate {the boost a bit only, but not power} and that's better than the 50% your in now. Then you'll need to get with "running rough" on the forum here and have it demandated properly.
