Have a volvo s40 2000. tuned by upsolute. running 10psi but its supposed to be 12psi with that tune. i want to bypass the TCV with a boost controller. which hose do i leave in the TCV and which two do i take off and link with a boostcontroller? is that how you bypass it? also what boost controllers do you all recommend. also could i just tighten my wastegate actuator a turn or so?

thanks in advance volvo people!

 

I do have a grimmspeed boost controller my friend can give me. its like 100 bucks normally. good quality
