Just an update.
Installed Catless DPs, and ER Chargepipe with stock DVs (waiting for Forge DVs to arrive).
At same time had Inlet valve clean (no prev. clean and 90,000km on ODO), 6 new fuel injectors (was getting misfires in 3 different cylinders and they were -09 so needed to replace all), new spark plugs and coils.
I'm now running JB4 Map 2.

Amazing difference, I think mainly due to the inlet valve clean and Catless downpipes. The throttle response is significantly improved and feels more powerful throughout the RPM. Very impressive change for such basic mods.

I'd like to thank DR-JEKL, Orlin and BMW86 for the push to change to catless DPs. Next will be getting an ATM 5" stepped intercooler and stage 2 fuel it once tax refund is submitted.

Thanks again, great result and very happy with the change.
