Super knock and hesitation on hard acceleration
UPDATE: Owner before me had the stupid JB+ installed, yanked that out, car is running PERFECT
Recently been getting some hesitation under hard acceleration in 2nd to 3rd gear at mid rpms. Doesn't happen consistently but often after driving car for fair amount of time. Seem to get good boost towards start of my trips, then can't even pull 10psi after a while Shadow codes currently: 2AAF - DME: Fuel pump, plausibility. 2FA3 - DME: No coding. 2FCA Fuel high pressure bei Freigabe der Einspritzung 30ED - DME: Superknocking, cylinder 1. 30F2 - DME: Superknocking, cylinder 6. MHD Stage 1+, intercooler, chargepipe, intake Running ACN91/CAD94 tune with chevron 94 Spark plugs were replaced 7000km, but thinking I may need to put in 1 step colder. Replacing coils within next week or so as well. Heres a log of a 3rd gear pull with hesitation https://datazap.me/u/kaden-oseen/los...-6-15-16-24-25 Thanks in advance guys!

If your stage 1+ it wouldn't hurt to do one step colder plugs and all new coils while your in there. Your fuel pump could be slowly dying as well, though the engine will cut fuel and then power if it senses knock so I'd start with the plugs and coils and go from there.
