I agree with Dude if you boosting hard for a long time you EGTs will start to rise you will never know this if you dont have a EGT gauge. Also if you have "WARNING" gauges you dont have to look at them until they start to chime. In my opinion gauges with out the warning feature are MUCH less useful since you cant always be watching them(Border line useless in my opinion since it will be the one time you dont look that screws you).


Boost warns at 14.1, Fuel Pressure warns below 50(If this warns im running out of gas), EGT Warns above 1400F, Oil Pressure warns belows 18 psi. In this scheme I never have to look at my gauges until they start making noise.


I have boost because you want to make sure you are not over boosting


I have EGT to make sure im not melting a piston, Detonation will also effect your EGTs.


I have oil pressure because I have so many oil lines id like to know if I have a leak.


I have Fuel Pressure because Id like to know if my return line falls off lol. And it also a back up fuel gauge.



I also have a defi setup up so I dont actually need the gauges to get the warnings just the sensors.


Actually my wideband warns too, so I dont really have to look at anything. Looking at gauges at 14 psi in traffic is hard


also my Apexi Avcr Map sensor went bad, so its been miss reporting boost for a while.

I won't go without my fuel pressure gauge, especially after going with a rising rate regulator.


EGT aint that important for me. You know as well as me that i'm not gonna be hitting a track anytime soon and I won't be WOT for minutes at a time. If I did that I'd hve 4 busted rims and a 3 dozen potholes smiling back at me.

Gauges I bought when I was new to boost (left to right in my pod)...
BOOST---FUEL PRESSURE---EGT


What I have now (left to right in my pod)...
BOOST---KNOCK/RETARD---WIDEBAND



I used my boost gauge the most from my original setup. The fuel pressure gauge makes for a nice gas gauge, but I didn't look at it too much. The EGT ran up over 1400 a few times. But that was only when the car was being pushed over 100mph and in full boost. I rarly do such high speed runs and only used the gauge to know when I can turn off the car (cooled down).


My vote: Lose the EGT gauge if you do not track your car (or drive 100+mph all the time).

My first time around with F/I, I went with Boost, EGT, Fuel. I track my car frequently. The EGT saved my ass several times, Fuel pressure just warned me when I am gonna run out of gas, (the gas gauge problem is fixed now) Boost, cause I often varied my settings manually, no electronic boost controller. I may remove boost when I get a new Controller, and add in a Wideband or Oil pressure.
