OK this might be a fun one...if you were to buy 3 optional gauges for your truck..what would they be....

 

Ok I'll bite it depends on your truck, but realistically if it's for your 99 then Primary gauge should be fuel pressure AFTER the filter. Secondary gauge should be EGT (exhaust temp) before the Turbo, Third with standard trans should be a Boost or MAP manifold air pressure gauge. With an automatic trans my third would be a stop watch. The stop watch? To see how long the automatic transmission lasts. Seriously though it would be a transmission fluid temp gauge. Acually I would install this as a FOURTH gauge as I feel knowing what your boost pressure is is important for many things.

 

I put fuel pressrue, EGT, and boost guages in mine. I wish i did put in a transmission temp guage as well.

 

Fuel Pressure post-filter, Pyro/EGT pre turbo, MAP/Boost. I used the trans temp readout before I got my new Goerend. Now I'm not too worried so I use backdown % as the fourth slot on my Edge Attitude.

 

Fuel pressure, EGT & Boost. Tranny temp for an auto trans would be close for the third gauge.

 

Since you said "extra three gauges" and I already have FP, EGT, Boost, and Tranny Temp - I'd go manual oil pressure, oil temp, and diff temp. I tow.

 

thanks....getting a post mount w/3 hole,,,,sounds like a good choice's of gauges.. been flying by the seat of my pants to long.... time to get control...thanks

 

I dunno............

Tough choice.......
