What do you guys think of these things? It measures HP and TQ, 0-60, 1/4, cornering G's, RPM relays and has sequential shift lights. I know numbers wont be that accurate but it will give a ballpark estimate at least. Any of yall have experience with these things?

 

anyone?

 

They are toys. Fun for a bit but I do not trust them and have seen them be dead on one run and 2 seconds off the next. You will have people claim they ran with one in thier car at the track and say it was nearly dead on, which is true I'm sure. But on the street thier accuracy is very hit or miss. If you want one to play with, thier cool I guess, but do not ever claim your time from one as proof of what your car actually runs, you need to go to the track for that.
