As far as RPM to full boost, it's around 4000-4200 RPM on a dyno in 4th.
Yeah i forgot to add injectors. What is the boost limit efficiency wise in the 2871? Should I go 3071 for reliability? I just want to get the best combination possible 400hp and fastest full boost. All that playing safe boostwise.
