Data directly from the Winpep7 printout:
rwhp = 351.41
rwtq = 336.25
Temp = 66.94 deg F
Humidity = 31%
Correction Factor = 0.99
I do not know what the calculated relationship is between "STD" and "SAE"

Peter,
I think that the 341 rwhp you were remembering was the 4th gear run on the Tundra that was truncated at 5,200 rpm by the speed limiter. That run yeilded 341.63 hp for Mike's Tundra with v1 tune.

Sorry this is off topic, but it keeps the MHP thread on top! ![Smilie](https://www.clublexus.com/forums/images/smilies/smile.gif)
Pat, STD is an inflated correction factor that NO ONE uses unless their goal is to inflate their dyno numbers. I believe you are referring to this STD graph of yours (not the Tundra's):

Here is that SAME dyno pull using the accurate SAE correction factor:

...and lastly, for reference, here is my 371 rwhp using the inflated STD correction factor:
