Can anyone give me the rundown about how invasive the smog testing in Salt Lake is? Do they look for mods (or just numbers), or do they care?? Is the stock emissions equipment sufficient on a GVR4? What are the gotchas(O2, Air Filter, EGR, etc)? Does leaning out work? I noticed a lot of modded cars out there on the last trip out so I really wonder how much they pay attention to it after the fact.
How drastically does the 2 point lower octane fuel affect drive-ability(coming from MS)? Does it affect emissions? Does the altitude have more effect than fuel? How much can I expect to adjust my fuel for driving (not necessarily just racing)?
Anything else I should know???
Thanks!
