My supra does not go over 5lbs of boost before it starts to dye out what can i do?

Answer 1

supra stock wastegate is set at 6.5 lbs an easy way to overcome this is to shim the wastegate actuater 10mm further out from the turbo body this will cause the gate to require more pressure before opening doing this on my stock ct26 raised my boost from 6lbs to 11lbs and I hit fuel cut at 12lbs when I really slam the throttle.
