factory gauge accuracy

powerjoker12 · Nov 13, 2014

How accurate are the factory gauges? I have the H&S mini max but it uses all the factory sensors for its readings. The gauges I'm mainly talking about are the boost, egt, and tranny temp gauges. thanks

My boost gauge is near dead on with my CTS, the tranny gauge I never see move after truck reaches normal temps, but the CTS shows the actual temp up or down. Yes the MM would be more accurate.

I'm pretty sure your CTS still uses the factory sensors just like my h&s.

I get your question...in most cases are they are close enough...probably not the answer you were looking for but they are usually fine unless you have a big build and even then a lot of guys use the factory sensors except sometimes boost (and that is often between the stages).

What I was trying to say is that with the cts, mini, or whatever I would rather see an actual number versus a little needle on a gauge that never moves. When Im n the mountains with my 5er Ill hit 220 and the guage doesnt even move but I know its hotter than normal because my cts shows it. I understand that they do pull readings from the same sensors but they are more accurate than those thingys on the dash.

Yea I understand what your saying mine does the same thing. I'm just debating on whether or not mechanical gauges are worth the money or if the mini max is good enough. I have mechanical gauges in my 7.3 and love them but I don't a digital display like my 6.4.

I have a MM and yes it is more accurate
