It falls of smoothly, no jerking it's just as you have described, 2 seconds is what I told everyone then it kicked back on and I got back up to 152.
Since I was in the middle of noooowhere Texas, I did it all from a text message through my wife who posted for me.

Plus, I have one of Jerry's latest tunes and mine does way better in a mile than 155!
Mine cuts out at 3/4 of a mile @ 160mph but the timing system says at 158 or close to it on the speedo but it's really 152.9mph so I feel like I'm 6mph off at that speed. It's just as you have described, just an easy blaaaaaaahhhhhhhhhhhhhhh then it's back on again. I swear I told everyone all weekend, 2 seconds just went soft but at those speeds, 2 seconds is about 450 feet and there is only about 3 seconds to make up what I lost. It's just exactly what happened in March when I was told the limiter was still on the car, same feel, exact same location on the track and almost exact speed. If it's as you both described, this is exact, spot on in every way what happened. When I said limped back in the pits, it was my pride not the car, the car runs strong as ever.

I would check your IAT's and start there.
All speed limiters are raised with our tuning.
The car sat for an hour before running with a low humidity and air temp outside of 74 degrees. It's 3 of us in the thread that all have the same feeling at the 155+ area with identical feelings of what the car does when the limiter turns on. There is no doubt in my mind after reading what has been posted that this is what it is. It's the same as in at the Texas Mile, same point on the track, same feel, sound and trap speed. I knew it and did it two more times on empty road on my way back home each time blllllaaaaaahhhhh then it would go again. It may be on the computer but I don't think it made it into the car.
