I am running stage 2+ (ko3) with reduced boost as no cooler (yet) but with cai bcs tbe and autotech pump internals. He did have the boost sat at 7 on the dyno, ran it a few times and then took it out onto the road for logging. Everything ran fine, so he has set boost to 8 just now while it's not terribly warm weather, but if I haven't sourced a cooler by summer, we will be pulling the boost back to 7. Unsure as to timing and fuel settings, sorry
