Hey Guys, I have looked night and day for some answers but can't find what I need. Im running the l28et swap with a t3/t4 turbo with megasquirt. I am looking for someone who has this same set up or close to it to see their numbers they are using for megasquirt. My car runs and drives but is running rich and leaning out under high boost. any help or links would be great thanks!

Hey guys, new to the forum here. I have a 72 Datsun 240z with the l28et swap out of I believe and 82 280. my current setup is megasquirt fuel/spark management 240sx throttle body 1 inch throttle body spacer high performance coil pack 4 row MSA racing radiator and electric fan t3/t4 garrett turbo manual boost controler custom 3 inch downpipe 3 inch straight threw exhaust fmic greddy bov centerforce df clutch rci fuel cell msd external fuel pump r200 with cv axel swap and nismo 2 way gtlsd with a 3.59 gear my question is what is a safe/good amount of boost to run? I have heard on the stock turbo 10-12psi in max but I have the t3/t4 hybrid turbo. The reason I ask is last night I took the car out for the first time (I re-did a bunch over winter) and the car hit 20psi. I wasn't expecting to get that much so I want to make sure its not over the motors limit, and if it it was should I turn it down to? Thanks for any help!
