Car was running great and boosting around 25psi with Lambda around .76 on my WB.
I noticed the temp gauge climbing so I pulled over and shut down before hitting the red.

When I got out of the boost I noticed the car was shuttering and running horrible.

After I shut it down I found lower coolant hose leaking, about 50% low on coolant.

I filled it back up and drove it down the street to let it sit overnight in a secure spot.

It did not overheat, and the temp stayed in the middle until I parked it, then it slowly started to climb.

It poured grayish smoke out of the tailpipe when I accelerated, but would stop as soon as I would hit boost.

In boost it runs perfectly normal, not shutter or roughness, and full power.

Again, I thought head gasket.

So, I just performed compression test tonight and I am right around 150 to 155 across the board.

What should I be looking at next (aside from fixing the coolant leak of course)?

I would not think a bad plug/wire or vacuum leak would cause the large amount of smoke that is coming from the tailpipe when I am not in boost?
