Just picked up new work truck. 2.7 ecoboost. Every once in a while it sounds like air brakes release. Before I make the dealer miserable is this normal? If it is what is it?

Blowoff valve or wastegate. It’s a forced-induction engine. Normal

Ok thanks. Have a 3.5, gravymakers grocery wagon that never made that noise. Two previous 3.5’s didn’t either.
I will say that little motor is sure peppy. It’ll run off and hide from the hemi I just turned in. Haven’t had the opportunity to see if it’s got the 100 mph limiter. Hope not.

It's eager for more at 105... I am not. Gets a bit of under steer over 90. To say the least. But it's down for 110+.

Normally a wastegate opens a valve in the turbine side that lets exhaust gas bypass the wheel. It goes back into the exhaust on the low pressure side.

Freaking hilarious I run 75,000 miles a year. My last gubment motors was my last gubment motors ever. Come with me after a 3,000 mile week and you can easily see which one you'd run too.

2.7 ecoboost tops out at 105-106 stock. Plenty of peddle to go faster, but the speed limiter doesn't allow it without a tune. My 2018 V8 is tuned to 130. I have only made it to 125.

Pat, Ford also accepted government money in the amount of 6 billion. So with that they are also government motors, so now what, are you going to walk.

At least they didn't take the gubment money and build factories in China. Doesn't matter if they were built across the street, my last three GM's were all junk. And I was raised that the sun rose and set on Chevrolet, you were some sort of retarded freak if you ever even thought of running something different. The 100 mph comment was the times running west or south and get stuck behind a twenty truck frac crew caravan running 40. You better have some zip if you're gonna get around the whole armada at once.
