More power all the sudden...
Yesterday I jumped in the car and had an extra 40 horse power all the sudden. Instead of boosting 30% into the white I was boosting 80% into the white. Couldn't resist a few spirited moments but I took it easy.
Today a little of the same until I selected E on my performance selector. When I switched back to S to show my wife the new found power it was gone.
My educated guess is that I was over boosting a little. I checked for loose or broken vacuum tubes but found none. Maybe my waste gate was stuck???

No, maybe I'll watch it tonight if it's on NetFlix.
I have no idea about the "wastegate actuator". So you are thinking that I've been running way low for a long time??? That would suck. I really know nothing about turbos other than how to check shaft play.

Actually, I have suspected that I have not been running full power. I have that ScanGauge and when I monitor the HP gauge, it has never registered more than about 170 HP. This morning I decided to switch to it to see what I was putting out and for the brief moment when I was on the highway shifting from 2nd to 3rd (automatic) the gauge peaked at about 258 HP right before the shift. Then I backed off because I was at the speed limit.

Dang, I feel like I have been abused, misused, and robbed.
One of those, "the more I learn the more I realize how little I know" situations.
People send me private messages all the time about performance and mods and I always tell them, I have no idea. Lol

The power doesn't seem terrible, little lacking but not too bad. I'd get a cheap boost gauge and see where it actually lies, there's a possibility that the dash gauge is inaccurate. I never trust any computer that is supposed to gauge the amount of power you're making through the OBD system. Doesn't seem much different than my car before I modded the holy crap out of it.

And to your question, most likely (i.e. the first thing I would ck) is leaks in your intake hoses.
