That is correct with only two notes from me. Lol. You can set the gtech to have a "0" roll out, so it starts straight away as long as you launch hard enough to start the gauge, it tells you to only get part way through 1st and then get into second and use it for a full rpm spectrum so that you have a good band for the gauge to work with, and that way you aren't going excessive speeds to deal with a high number of resistances air, wind, etc. I can understand that the dyno gives better results but my hp/tq numbers are down at around 100 or so?
