All the points above about the RSM meters are correct... they tell you what is actually being applied to the ground... or not in some cases ;)

Also, in my experience the G-Force type meters are actually quite accurate... so long as you get them setup right. But that's the ET side of them, not the HP... haven't used the HP feature too many times... maybe I'll try it out on the Eclipse when I get the turbo back on :)

And don't forget what I said before about Hahn using his 150 shot to get over 505WHP... that should tell you something! ?Just think about it.
