Me and my friend were riding around and used his GTech on my stock Redline.

Horsepower:
168 (hit rev limiter twice)
196
223 (?Glitch?)
198 (Good enough for me)

0-60:
7.55 (crappy launch)

Hopefully i'll get pictures/video next time......

low 7 second range is what I managed when I tried using the G-Tech pro last summer, which I found disappointing but I also had a devil of a time trying to launch correctly. What strikes me as odd is that I had a Silverado 5.3 V-8 that I had some mods on, when I used the G-tech on that thing I registered a 0-60 of 6.5 and this car feels much quicker than that truck. Which G-tech did you use and how did you mount the unit? The G-tech pro has a very short cigarette lighter adaptor thus was hard to mount on the windshield. I may try again when I get a cigarette lighter adaptor extension cord (say that 3 times straight!).

I think the strip of road you use has to be perfectly level for an accurate number. I went driving by the areas that I ran my last tests (with the sub 6 second 0-60's) and noticed a slight downward slope, so that probably explains the much better than normal numbers. I've attached a link to a run I did on a surface that seemed much more level, so this is probably a better representation.

So which one is the real 0-60, the dissapointing sport compact magazine 7.2 or the car & driver, motor trend, Road & track between 6.1-6.3. And those this have any to do with cars that have not received the ECU upgrade yet?

Hell, I would have thought a lot less than 7 sec, car & driver they test 5-60mph roll on real street driving acceleration and they gave the RL 6.4 on this test. So I would assume even without launching the car the times would have been a lot lower.

It definately hovers around 6 seconds plus or minus a few tenths. I can't wait to get my summer tires back on and try out some more runs when the salt is cleared from the roads.

Tires make a huge difference in times. Repost after the summer tires are back on. Please. :D

I used the GTech to get a HP and Torque curve today using the technique the book recommends. If you go to the link, disregard the 0-60 time as it instructs you to launch easy and only rev it to 3K in first, then shift to second and floor it until redline.

This technique measures "net" horsepower which is different and lower than getting wheel HP from a dyno because the car is experiencing drag with the GTech, while no drag on a dyno.
