Is there a actual A/F gauge that is accu and will fit in my gauge pod

accu? accurate, is that what you mean? If its a wide band, then its going to be acurate to 0.1 a/f reading... usually. and if it will fit, measure the diameter of your pod, and buy one thats the same. The usual is 2 1/16" and i believe 2 5/8" diameter.

go with an EGT gauge. better off, air/fuel bounces around a lot.

The AEM wbo2 is 52mm or 2 1/16. Fits my pod just fine.

Some gauge pods you will need to file/sand the holes bigger, depending on what gauge it is. For example, i have the 3pod gauge hold from Lotek and my Knock Gauge from Caspers fits in the holes nice a tight and its a 2 and 1/16th gauge and my other two are from Stewart Warner (boost and oil pressure) and they to are the 2 and 1/16th size but i needed to file the holes a bit bigger (like a very very tiny amount) and then they fit in nice and tight. because the difference from the 2 and 1/16th to the 2 and 5/8th is a big big difference. And i suggest this gauge to you (it is made by Stewart Warner).. very very good company, you find their gauges in a lot of cars that come stock with boost or what ever.
