My 04.5 has had a Garrett powermax stage 1 for the last few years. It has ed 50hp injectors and I run a smarty on sw2. The drivability of the thing sucks and keeping egts down can be a challenge especially towing. Its gotten worse the last few months. I was thinking boost leak but can't find it. My next guess was to check the wastegate. The he351 was shot, and we wanted to upgrade was the original reason for switching to the Garrett.
Does anybody have any ideas why we're having troubles with it, also would we be better going back to an he351?
Thanks
