That particular set-up is out of the car at the moment, but the last time I G-teched the car in hp mode it made 165hp (I beleive that's wheel hp minus wind drag). And my vehicle weight was accurate. The 1/4 mode is always a dissappointment because of traction. I just haven't found the right place to feel confident enough to properly heat up the tires and then do several runs without fear of traffic and the boys in blue.
But I think the hp reading is a good indicator. Just wait 'til Larry gets my motor done!
