When I bought my Laguna Seca, the supplemental book was missing.
I have one now and it is no help.
The last three times I took her out the performance gauge would not stay turned off.
After a variable amount of time it will come back on and shoot out numbers and flash the LEDs.
The past two weekends didn't offer me a chance to calibrate it.
Last Friday I drove it to work so I could drop by the dealer since it is a CPO car.
Do these things really work, or are they crap?
