ya it will boost higher. but an hx35 isnt efficient over 30 lbs anyway. i have broke a shaft in a 35 by overspinning it

on the turbo there is a small maybe 1/4in. rubber line. u can fold it over and put a small hose clamp on it. or cut it and stick a bolt in it

I would say so. Is it smokey at all? Does it spool up quickly, get to 20psi fast?
Could be a wastegate issue.

Imo, make or buy one of these so you can control the boost instead of pinching off the line or blocking off the line. Better than blowin you turbo and havin all those nice little pieces go through you motor.

It smokes a little when you accelerate hard and when it goes into overdrive, if I'm at 35-40 mph, it'll smoke pretty good until i get the RPMs up
