Ok TL&DR,  40k, 2010 SHO non-pp, Torrie tuned.
3bar sensor
.28 plugs from his site

Is the following normal behavior ?
-switch to manual shifting..
-drive car until 3rd gear is at a steady 3500rpm on a flat road.
-keep at 3500 rpm 5 or so seconds
-hit the accelerator hard and fast .. *BUT NOT* enough to down shift it.

What I feel when I do this is the car begin accelerating for 500ms,  then it wakes up and the power level increases and we continue on until I take my foot off.

does anyone else notice this behavior on their 2010-2012 ?

The difference in power before it 'kicks it up a notch' is minor.  Not enough for my wife to notice or other drivers.  But I can feel it and have logged it.  it is a very small blip for a short period of time.

Torrie took a look and did not see anything in a few different data logs and there were no 'errors'  he could see, misfires, spark issues to cause the vehicle to retard things.  it just has 2 different power levels for a short half a second when you get into it in this fashion.

2,3 gear is most predominantly where you really feel it.  4th-6th not so much

ideas ?
