This is an older thread and there was a question asked that I could not find a answer to which was what do the readings mean.. I know there are diff setups such as stock car chipped car exhaust mods etc. but on a stock setup what are the ranges for the readout. I have a 90 C2 with a chip and J pipe so this may play into mix but what should stock settings be. I am looking at the replies and see many diff readings.. Thanks Randy
