my Wagon is sluggish, Always has been. It's rare for my RPM's to go over 2,000 unless I really push it. Freeway driving is mostly with the pedal to the floor Cruising 70. if I push it I can get the RPM's above 2,000 but thats far and few between...Idk if my Turbo is not kicking in or not. I certainly cant hear it when I have the car running like I can on the cummins and powerstroke albeit they are huge engines.. What should I be looking for on this? I noticed a small pass thru bolt with a hose on it near the bottom of the Turbo, and there's a Vac line to it to that branches off and goes to a metalic Round part near the front under the air cleaner. where it shoots to after that i dont know.
