for a TD42T .72 - .78 and over depending on setup. can run alot more than that on a modded pump and turbo. TD42Ti .68-.70 this is a bit touch and go and should be done on a dyno or by someone who knows their stuff. sorry cant really help with the NA stuff, havent done much with them. I barely ever touch the max fuel screw, most of the tuning is done on the boost compensator and timing and boost. then you can maybe give a little max fuel.

(this is general advise and should be done in conjunction with pryo boost and afr readouts on a dyno)
