Why should I get a different boost gauge?

[morebiodiesel]

I'm getting ready to order some gauges.

I was planning on getting an EGT and Tranny temp. My truck is a 2005 and already has the boost and tranny temp but I figure the tranny temp is nearly an idiot guage because it never seems to move when I'm towing and I know something must be getting hotter when I tow up Black Mountain NC.

As for the stock boost gauge, it's readings seem snappy and reasonable. Why do people buy an after market boost gauge if the truck already has a functional gauge?

Also does anyone have a strong opinion on which EGT gauge is better? I plan on ordering gauges from Diesel Manor because they have such great on-line support.

I was under the assumption that the stock boost gauge is very accurate.

This is a little off topic, but do you live in black mountain?

I live in the Fairview/Reynolds area. And nick(HVAC Supertech) lives in fletcher.

As for your original questions,

Yes the factory trans temp gauge is just an idiot gauge. Your right about that.

As for the boost gauge i think its pretty accurate.


But i'm sure someone with a little more 6.0 will be along shortly to deny or confirm that

The factory boost gauge is fine. It always agrees with my Quadzilla. The trans temp gauge is worthless, though. It always sits in the same place as you noticed. My trans runs anywhere from 140-150-something empty and can run 175 towing a heavy trailer. You'd think the factory gauge would move a little with a near 40 degree difference.

You'll be fine with any quality set of gauges, Auto Meter, DiPricol, ISSPro, etc.

I live outside of Raleigh but we often camp near Asheville which takes us up Black Mountain.

Concerning the external Boost Gauge the consensus seems to be that the factory gauge is accurate so I guess I'll go with a dual gauge setup of EGT and TransTemp.

Yup the factory boost gauge is fine
Tech 1002 the reason the Commander and the factory gauge agree is the both read from the MAP sensor and get the same reading

[tech10002]

Yep, I know, but the map sensor is very accurate unless there's something wrong with it. I know plenty of people with mechanical boost gauges, and they all agree with the factory one.

True i wasnt trying to make it sound like they would be different or anything. Just pointing out that the readings come from the same place

If the boost uses the same sensor and is fairly close then why is the trans temp so far off? I'm assuming trans temp uses the same sensor as well.
