Any tips for setting the pump up guys

[kev_boosted]

Later on I may goto a Bosch pump but that will only be if I go bigger turbo or front mount,

Just trying to figure out if I'm on the right track to getting a stage one tune.

But worried that I may have wound the boost correction screw out to far.

I know screwing the pump pressure screw in adds fuel

Does screwing the boost correction out add fuel or make it run leaner.

I know with petrol engines. Leaner spools better
