Log Review!

Could someone take a look at these two logs. I've gotten a misfire now twice on cylinder 6. I'm full bolt-on running MHD stage 2 v5

DME codes that appeared when i scanned were: 29D2
Shadow codes were: 2AD0, 29F4, 29F5, 2AAF

Looking back how is it possible that I peaked at ~19 PSI with just the mods in my sig. Isn't that dangerously high for the stock turbos to handle?

Fuel Pump looks to be taking a shit.. I've been told it should not drop down in the 50's and yours even gets down into the 40's at one point..

are you running ethanol? lpfp is really struggling.

50s is fine... 40s is too low. So yes OPs lpfp is struggling.

19psi is not inherently dangerous on stock turbos OP.

Your bank 2 lambda seems to be consistently lower than you bank 1 lambda..

Sounds like you need to get a LPFP soon... Get Stage 2 and run E40.

Does that imply Bank 1 is too lean (too much air compared to fuel)??

so is it definitely an issue with lpfp or could it be o2 sensors..?

With your fuel #'s hitting the 40's my .02 would def go towards it being lpfp, but others may chime in to verify..
