....and dave i can't argue with you because you have so much more knowledge than me on this topic. but i still don't believe it, the sensor should do the same thing that the actual guage does, it just converts it via voltage. so any delay would be within miliseconds.. and I would say that the chance of the unit failing is just as likely as the guage failing. but then again i have never run both guages together to see the differences. so ....you win....damnit
EDIT: i have mechanical...but it was only by mistake! i thought it was electrical.
