Hey everyone
Got my MPI stage one installed on an Apex,rode it for tuning and then one full day at altitude. It ran flawlessly. Parked it in my garage.Today i get ready to ride and its running super lean just at idle,and will not take any throttle or it dies.
I check for obvious vac leaks,then pull plugs all look good except last one. Boot was wet and smells like coolant.
I'm guessing headgasket. Any body seen this before. Never overheated it and with 10lbs boost headgasket should not be an issue.
Running 6-10,000 ft with 50/50 mix on fuel.
Any ideas?

Make sure you didnt blow the throttle bodies off from the engine. Its very easy to do and sometimes it only blows one end of the rack loose. you may have to slightly pull on the throttle bodies to see if they are loose.
