Hey guys. Hate to bring this up from the dead but i dont want to start another thread on the same topic that was mentioned but i dont think i saw an actual answer to solve this issue.
Quick back round. I have a ‘16 golf r. I installed a hybrid turbo, PR MPI, and PR 3.5 lpfp, and the -6 fuel line from PR. Im running eurodyne maestro.
I get this P308d code and it stays on. from day one. I did all the mods to the basket for the pump too. Nothing has changed. I clear the code and it comes back a little after. Even if i drive normal.
Also when i do the logs, right around 5k the car seems to be “breaking up”. Cyc 2 gets the misfire. Just recently i went back to ED stage 2 and the problem still exists.
Ive done a compression test. All cyc were right around 200 psi, changed plugs to brisk er10 gapped at .022, installed new rs3 coil packs. When indid the mpi the valves seemed to be fine, no build up as i was surprised.
i do have the supporting mods for everything so that can be ruled out.
im definitely lost at this point. My tuner never had this problem but he is trying to help.
