Its running on bcp6es which is what the TT plate recommends left the gap as factory because the plate did not say what do you recommend, cant say for sure about the boost as i have not got a gauge in yet but if it is as it should be its only 6.5 psi. It certainly doesnt eem to be missing just really hesitant as i said almost like it is missing and when you give less throttle it cures itself.
