I installed everything as indicated here - fyi the STi restrictor pill did not need to be drilled. It was already slightly larger than the 0.043" drill bit.
It boost creeps badly - in 3/4/5th gear at about 5k it fuel cuts like a mofo.
Factory boost guage is reading about 18.5 psi.
How the heck can this be fixed?? I've read - -use cat, port wastgate, tune it out. Does anyone really know?
I hate to ty 4 differtn things that don't work. Anyone else w/ similar issues?
