Remember this isn't petrol - there's no AFR to worry about, running lean doesn't cause any issues, it's running lean all the time! You can turn up the turbo, but you wouldn't achieve any more power than standard as there's no more fuel to go with the air... You can wind up the pump a bit without winding up the turbo, but as a rule, you'll want to adjust the two together...

You can achieve around 135-145 on a stock turbo and tweaked pump if you do a hard tune
