Anything over 20psi and I'd have to think you're leaving the efficiency range of our stock units. 17.3psi seems a bit low for FBO+meth, i'm currently topping out at 17psi or so midrange without catless downpipes or meth.
When I installed the RB turbos,I got 17.6psi only,I dont know whats wrong with my car.when I back to the stock turbo,I can see 17.3psi in the datalog.
my pwm its work now,when I upload the new map.
I see my log the fuel trim all maxed sometimes,like the log.
I run the stage3,
start boost map1(60%) map2(85%)
limit:20psi
