Good evening folks.
I am nearing the end of tuning on my x47 setup. On Eastern Washington 92 octane I am hitting right below 250 HP per Virtual Dyno, but I am seeing knock pretty consistently across the cylinders. Mods are in my profile but a quick and dirty are:
CPE intake -> x47 (with IWG75, Pumaspeed intake pipe, GFB DV+) -> Stock hotside -> Whoosh Intercooler -> Stock coldside
Stock exhaust manifold -> Mountune Catted DP -> Thermal R&D exhaust
I changed out spark plugs to 1 step colder just to see = No change
I changed to several different gas stations and brands = No change
Ideas on how I can squeeze more out of this? Would changing out the hotside help? (either full or just the metal part ala mountune)
