Question: has anyone had an issue with getting a CEL code for P0231 (fuel pump secondary circuit low) & P069E, which is trigger by 1st code, when going WOT? I was on track a couple of times and gotten the CEL once I hit around 120mph.

I'll be in the shop by next week for diagnosis, but curious to know if anyone else had the experience. I'm modded with supercharger, cam, flex fuel, and JMS voltage booster. Was tuned for up to 60% ethanol. Tuner did a revised tune, used 40% and even 19% blend and still same thing. Tuner thinking it has to be what the code is indicating, an electrical issue.

Thanks!
