Sounds like it has performance cams in it. Too bad it's not supposed to sound like that.View attachment 215441
Finally got my trackslag back from ceramic coating. Looks fantastic! Got an appointment booked in a couple weeks to get the XL and whatnot installed at last.
Went to start it up yesterday and the idle is super rough though. Drives fine under throttle, but does not sound good in park/reverse. Thinking maybe the IHK27s I got have fouled out already? Can't find some of my plug tools so I gotta wait to pull them and check. Worried that maybe it's injectors instead--I assume the UM tune is pretty much DI-only at idle?
