I look at the Oil Temp and that is about it .. as far as having anything useful while driving though I don't think it is up to par since you would have to take your eyes of the road and put them way down by the shifter
.. That is why I did the ADM Boost gauge just under the speedo/tac ..
BTW .. if I were to get a ZL1 (which has the boost gauge in the 4 pack gauges), Id still do the ADM or some other gauge that would put this somewhere a little more convenient.
