Any ISL400 Boost in Park Mode?
I have an ISL400 in an '06 Endeavor that has been sitting for awhile, and fired it up today to check it out. Happy to say that it turned right over and ran well. All fluids went to their normal temp/pressure ranges, and it sounded like it's ready for a trip.
However, I noticed that there was no boost pressure whatsoever, either at idle or when I kick it up (maybe ~2000 rpm or so) in Park. Unfortunately, I am not able to get it out on the road yet to try it under load. Don't remember what it used to do, and if 0-boost is normal under no-load conditions.
Should I worry yet?
