A/F Gauge or EGT/Pyrometer Gauge?

[JMSinMaryland]

I was all set to order an Autometer A/F gauge to compliment my TRD boost gauge but now RayCarlo posts that it's not worth it and just for looks? Im not into getting a gauge that isn't effective and is all looks. Does the A/F not do a good job at properly reading the mixture? I heard when you are watching your boost rise your A/F gauge should start moving towards rich? Would a EGT/Pyrometer gauge be more effective and how exactly would I determine the a/f ration with an EGT gauge? Would it be stoich would be ____ degree to ____ degree while lean would be ___ to ____ and rich would be ___ to ______?? I think I'm also going to be getting Danny's pod that fits below the ash tray and put in oil pressure and fuel pressure gauges there. Now advice on A/F vs. EGT please. TIA. Jon.

i tried installing an A/F gauge in my car, but it never worked. another thing that i get from others is that autometer A/F is pointless. it is not accurate unless the engine is in full throttle. if you want an accurate A/F gauge you might have to go with Greddy or something that requires one to make a custom bung for the A/F meter gauge.

i myself will be siding on an EGT meter in my ride.

Basically any plug in A/F gauge will not be 100% accurate. You would need a full system which can cost upwards of $300. The A/F is for looks but if you have the SC and are running higher boost it can prove useful.

I'm not sure really how much more useful EGT would be.

I'm planning to install my boost and A/F ASAP so i'll let you know what I think of it.

EGT is just to measure how hot one's engine is going. there are times when i come home gunning it up the hill, i find that the downpipe(right below the cat in the front bank exhaust manifold) is glowing red/ dull orange.
