Im beginning my first turbo build, and today I decided to dig a bit into what gauges ill be using. I want the interior to be clean and simple, im not interested in having a ton of gauges - im going to have a Sard Stack cluster displaying oil T, oil P, water T, and of course speed and RPM's, also a custom dashboard with three gauge ports where the vents are located on the OEM panel, ill have a Turbosmart eboost2 in one, and the other two are undecided. What I want to know is if I use a wideband AFR, is an EGT gauge necessary? If not, ive been reading a bit of the pro's and con's, what do you guys personally prefer to use over the other?
