i know you can never get as good of times on the street but if you can't reasonably go to a track a g-tech seems the way to go.. any thoughts?

they work as a tuning tool b/c they give u numbers to improve upon, unfortunately they're a bit off, usually they give u a time thats a bit lower than an actual track time

It gave me ETs that were pretty close but the MPH was 10 mph high consistently.

The gtech gives you the speed at the end of the run whereas MPH at the track is averaged over the last 100 ft I think?

Not at my track as far as I know. On my race bike, I had a peak feature for my speedo, and my speedo peak was always the same as my MPH on my time slip...

i ran with mine down the track befor many times. It would give me a reading about .1 to .15 seconds faster, and about 5mph to high.

And the track averages your mph over a distance at the end of the track. Dont think its 100ft though.

I use it for measuring 2nd gear power so I can get a feel for before/after.

ie before (BPU) = 350hp

now (SP58gtBK) = 295hp

:(
