I don't have the restrictor pill in as per interrupt style install instructions from Perrin. Have not set more preload on the wastegate. I am running the normal XPT map and adjusted the settings myself. I would be interested to know what changes are made to the XPT map for running the GM BCS as it should be the same.

From what Jeff said, the most important table when adjusting for interrupt control is the Dynamic burst. Cutting those numbers in half was what was suggested and that certainly did cut the spike out. WG duty is somewhat important but that one is honestly easy to tune for. I am just wondering how many of the tables affect the wastegate operation other than those.

My plan now is to reflash to the stock map and set the EBCS up in bleed mode and see if the boost normalizes. I have already ran the WG straight from the Boost source and I got an exact 8 PSI. I want to run an MBC at about 12 pounds just to rule out any possibility of a mechanical, non-ECU problem.


P.S. Taking advice from a guy named "Dumdum" has historically not been a good idea. But honestly, I do appreciate it.
