GTech
I saw this "tool" in Summit's catalog. It looks like a radar detector and plugs into the cig lighter. It allegedly tells you your HP, torque, etc. It is a Gtech by Tesla(I think). Anybody heard about or used it?

hey jj, I've seen and heard about it. although i've never used one, it is a good basis of how the mods you add compare. it might not be accurate, but it is a "tool" none the less to gauge the progress of your truck. Ask Neal "the horsepower freak", I believe he's got one. I've wanted to buy one ($129) but I think I'll get my pulleys first.

I have used a Gtech with my wifes Camaro. They are surprisingly accurate compared to the track (we ran it on the track to check it). Expect it to show you running .1 to .2 faster in the 1/4 and 4-5 MPH faster at the traps.
As was previously mentioned, whether it is accurate to the track or not is irrelevant if all your looking to do is see a relative improvement for mods. Then just run on the same road in the same weather and look at before & after.

I have one and it's a great tool. The reason it reads different than the track is your speed is averaged over the last 60' at the track,while the G-Tech gives actual MPH at the end of the 1/4 mile. I haven't compared it to the track,I'm happy with how close the results are.

Hi jj,
The G-Tech Pro is that it is not a dyno, will never be as accurate as a good chassis dyno, and of course it only costs maybe 1/10th of a percent of what a good chassis dyno costs. For the money, it's a decent tool if you know it's limitations going in.
You have to be very careful each time you mount it to carefully level it and mount it the same way each time, for best possible conparisons.
For it's price, MSRP $139, it's a neat toy and can be a fun tool. You just have to remember that it has only 1 inexpensive accelerometer on board so it can only look at 1 axis at a time instead of all 3, which is a limitation in this type of device. In this case, that's fine for it's price!
At best, and I've not seen this happen consistently, but at best, we've seen them be within 2-3 tenths on the 1/4 mile ET's, and they'll always read significantly higher in trap speeds, as jstang correctly explained, due to the way it determines trap speed versus how it's actually done at a drag strip. So the trap speeds will be anywhere from as little as 3 to as much as 8 mph off, giving a somewhat optimistic speed number compared to what you'll get at the drag strip. Again, as long as you know about that going in, I think that's fine for it's low price.
All in all, for it's price, it's a great little toy that can be a nice tool for looking at approximate performance levels. I don't have one currently at the moment (I can't remember where my last one got to), so I need to get another one, too!

We didn't test that out but I would bet it is calculating those based on the acceleration through the run and the MPH at the end so I bet they will be fairly close.
I'll ask my buddies that have one if they have tested it against a chassis dyno. Keep in mind a couple of things: first, I would guess the calcualted numbers will be rear wheel and not crank numbers and second, even dyno to dyno numbers can be markedly different so one test may not make a conclusion.
