The FPCM is not getting the response it’s targeting between the JMS and AUX PUMP CONTROLLER trying to push pressures YOU are commanding. I wouldn’t know, but it seems like you and KATECH are on it and are on track.

I, personally even in light of my complications (some of which I have admitted could very well be self-inflicted - I don’t KNOW FOR SURE, but it is a fair possibility), I like this module and bucket. Even with a new competitor, that seems vastly overkill, I appreciate the apparent engineering and quality behind it. I can also see potential for easier installation, but for me, the price isn’t worth the apparent capacity nor the over-engineering (I’m not taking ANYTHING away from any part of it - DEFINITELY PLATINUM QUALITY) are such it would be worth it over this module. I’ll never want the power it supports and don’t need a billet bucket, though it’s SUPER BADASS. MANY KUDOS to them.

Yeah I run the JMS right now still. I called Vaporworx just to see what they think about it and they indicated I shouldn't need it either, but they also indicated that the increase in duty cycle tables that is on my setup may be causing the issues as well and to either turn it back to OE values or lessen them even further.

Truthfully, I am only still running the JMS because I was under the impression that the DW400 pumps do not like the increased fuel pressures that these cars run in OE config and I was also looking for more stability in voltage. Based on what I told Vaporworx as well they were also recommending that I turn down the JMS to 16 volts and see how it does as well, because as of current I have mine commanding 17.47 volts.
