A pal of mine has a T34 .48 fitted to a std 2wd engine with a -31 actuator , the car doesn't make much boost even if you heavily preload the actuator arm , its running an amal valve currently .
Im wondering why , ive read a bit about jetting these to increase held boost , is this the next step or should he dump the amal valve and connect the compressor to the wastegate to control boost , hes looking for 1.4-1.6 bar on greens . ???
