5K hesitates, stumbles, pops, overboost?

Thank you to all of you,

the Michelin Man hose looks fine (twisted and bent it, all rubber looks
close to new). I twisted the metal caps on the spark plugs, couldn't get
them to slide but again, the wires look good, not brittle. The Intercooler
looks fine but I didn't take it out (yet, when I do I will at least put
those hose clamps around it and JB weld on the seams).

As for the sound: it is more of the sucking kind, sputtering of sorts, not
what a misfire sounds like but it goes with the car loosing all power...

I will keep everyone posted, thanks again,

Christoph
