Keep your car a sleeper. Don't put those guages on the "A" pillar. You know how much boost. 4.8psi. If you are going to be running the street kit or race you won't be running lean because the ECU handles all of that. You don't really need guages. But, if you want them, then do, oil temp, oil pressure, and a/f ratio.

Boost guage can also be a good guage to have..Significant changes in vacuum can signal a problem w/the setup, such as a vacuum leak or idle bypass problem..

If you have a car that is turbocharged and supercharged, why wouldn't you want a boost gauge? That and the A/F gauge are probably the two most important ones.

KEEP an eye on your charger! Yes we do know that we should always be running at the same PSI, but how do you know whats going on under your hood while your driving on the highway? My point is, the gauges act as safety gauges for the charger. They will let you know if something suddely goes wrong. For some wierd reasson, you suddenly run completely lean. THATS NOT GOOD! If you don't have a gauge showing that, how would you know (until you hear your motor blow) I was told that the two gauges you SHOULD have are a boost gauage (make sure your getting all the power you should be getting) and an Air/Fuel gauge (to keep an eye on your lean/richness) Hope that helps ;)

On topic...I'm not arguing your point, but why aren't A/F gauges accurate? I guess the better question is what would it take to make a A/F gauge more accurate. I guess I would want four...A/F, boost, fuel pressure, oil pressure, and oil temp is also handy.

Off topic... Chris, why can't we have the kick ass smiley in your sig???

I am not sure why, something having to do with the voltage of the O2 sensor and a guages inablity to read it. I have only been told that they are just flashing lights and often not a good indication, but I don't have anything solid to back it up. The person that told me is the only one I trust to work on my car but me, for what that is worth.

That one is special to me. :)

Basic A/F guages such as Autometer just read voltage coming from your ECU to give you an A/F reading..Because your ECU is constantly making changes to ensure you are at a proper A/F ratio, this voltage fluctuates constantly, making the readings not as accurate..

You should look into a wideband O2 sensor if you are looking for a tunable and accurate A/F reading..They employ their own O2 sensor, therefore making it a much more solid reading since there are no adjustments being made through the sensor, just monitoring..

AEM makes a pretty affordable wideband setup: AEM UEGO AFR ..check it out..

thanks for everyone's help, i think i'm going go with just air/fuel ratio and boost in the A-pillar and a fuel pressure guage under the hood.

Well, I use the Nology OBDII Scan Tool for my guages. I monitor Intake Air Temp, Coolant, real time RPM, Intake Manifold Pressure, O2 sensor voltages (front and back), absolute throttle position, and numerous others. Manifold pressure is my boost, O2 sensor voltage is my A/F, you just need to know how to convert the readings to PSI and Lean/Stoich/Rich readings.

Everything is in the car. I did it this past week. I wouldn't mind trying a bike. :laughing: We can meet up when it's broken in.

The best to get are boost and exhaust gas temp. You could do oil pressure or fuel pressure as well but they are not as important.

where did you buy it from?

Just to let you guys know, A/F gauges are not that accurate. It is much better to use a fuel pressure gauge, that will be much more accurate.
Don't you mean a pyrometer? (egt) :laughing: ;)
