i bought autometer ultra lite trans, pyro, and boost gauges with a a-pillar mount. any suggestions on where or how to mount them? i have done a search and seen pre and post pyro ... whats better? and i have read that the trans has a plug i can pull out and stick the probe in will this work on my truck? and should i get the piers boost fitting for the boost gauge?? i know this is probably getting old all the gauge questions but some help would be greatly appreciated thanks for all the input -- drew
