Recently I had done a lot of work on my car. In forth taking it to scoffs for a power reading. The fuel was fine to about 20 psi. Then my turbo went bang, my issue is I've replaced a t25 tomcat with a t2 to get the car running. Running 7psi it's lean 13.2@ wot. Cars had a new fuel pump, new fuel filter, adjustable malpassi fuel reg set at 6 psi. Carb spec, 120 main, 0.9 ac, 1.7mm needle valve, second stage 1.3mm. Wtf is going on? Why is it lean
