i just installed my new manual boost controller and i used the stock turbo outlet line and wastegate line. it slipped right into place. my question is, will the BC get oil in it from the turbo outlet line if my valve cover isnt capped with a breather? also, i turned the BC up b/c i only got 10 psi when i put it in and i finally got ~15 psi in 1st gear but in 2nd gear it always settled back down to ~10 psi. then i blew off my inlet hose and when i reconnected it i gave it gas and it went to 15 psi but it kept going and i let off it b/c i dont want to blow my engine. would a leak in my crossover pipe be the reason i get full psi in 1st but then it goes to 10 psi in 2nd? i was thinking that in 1st gear the RPM climbs so fast it doesnt have time to leak exhaust out of the pipe but when the RPM slows it has more time to leak out the exhaust from the crossover. could this be the cause of my boost deficiency?
