Anyone else with actual experience dynoing a Auto? I'm trying to gauge if any other tuning shops dyno in 2nd or if they all use 3rd like I want my place too

I asked a local dyno about autos, he said you can unplug a solenoid so it wont kick down. Is that true?

You could disconnect the revolution sensor on the trans that'll stop the kickdown happened to my friend when had the VBmod done and they didn't plug his sensor in - no kick down.

Could someone help with interpreting the results? Is the red line stock and blue line with y-pipe? It looks like the y-pipe has less power up to about 5400 RPM, then the y-pipe has much more power all the way to red line. Am I missing something? I like to add a y-pipe to my automatic car, but based on the above result I don't think I will benefit.

Blue was stock, Red is with the Y pipe
Following the Red line I get more torque and more power earlier in the curve - it looks like a 10kw gain across curve (3400rpm to 5000rpm).. when my VI (when fixed) kicks in at 5100rpm the curve will look even better.
FAVOUR PLEASE Can some convert my torque figure to the torque figure you guys use so I can compare.. my maths is bad

after dynoing hundred of automatic cars, one learns where the kickdown is. Once that is known then the test starts from there. There arent many auto trannies that will not kickdown. as for dynoing a car in 1st or 2nd gear... that creates a lot of distortion and movement on the cars on the rollers. Also its very stressful to the straps.
We perform our tests on 3-4 on 5 speed cars and 4-5 6 speed cars. When doing steady state tuning we like to work on 4th gear.
