I was thinking about this post today. I sometimes use my G-Tech Pro to test for changes in horsepower/torque after engine mods. When I do this, I want a very long RPM run in the same gear with no wheel spin. The way I do it, is to put the selector on th small green dot, assuring a start in 2nd gear. Since I'm doing a 0-6000 Rpm run (90 in 2nd or there abouts), I look closely at my radar detector and visually as well to try to avoid "federales" (what they call the federal police in Mexico and now a generic term for police in general as used by some old Texans). After starting out on the small dot and running up to 50 or so, I have to put it back down to low while still at WOT to hold that 2nd gear. It won't shift into 3rd untill I put it back into drive (either dot). That allows me to do a 600 RPM - 6000 RPM test on my G-Tech. It won't be very fast for et or anything else since the whole run was in 2nd gear. It does give a fairly good hp/torque graph for existing conditions on the G-Tech.

Remember though that the hp/torque figures from the G-Tech include losses for tire friction, wheel bearing friction, all drive train friction and aereodynamic losses. Anyway, I did think about this thread while I used my Cruise-O-Matic dual range to start out full throttle in 2nd and hold it there to 6000 RPM.
