Stoich question...my 98 has 14.62857, every other year I've seen has 14.737?
Why is there a difference in the Stoich AFR in 98s compared to other years? Mine has 14.62857, and every other year I have seen has 14.737. Does this make any kind of difference? Does anybody have an idea why GM did it? Would it hurt to set mine the same as the rest of them?

I'm guessing it has to do w/the region the car's sold in maybe? Like depending on if they use reformulated gas?

My '03 truck PCM has 14.684 for stoich.
Edit does not have these... might not be much familiarity with them yet.
Has anybody noticed if the O2 High and Low values are different on the ones with a different Stoich value?

say its setup for like 14.6:1 and i want it to run 14.8 (2% leaner).
Just an educated direction on how to tweak this parameter would be cool.
