2) Pay 200-300 under the table.
3) Get Hot Rod Status. Must obtain letter from Mazda and/or convince drive clean centre.
4) If you have a lowered car and it can't get on ramp then you only do idle test (same thing for AWD cars)
I want to avoid option 1 and 2 because I think they're bullocks (will put new spark plugs and good gas though).
So Any experince getting a letter from Mazda? Which delearships did you guys go to? I know of a few test centres that will test as hot rod even though ZE is same displacment... as long as i have letter saying engine is diffrent from stock.
Also i do have a lowered car on puny whels so it's is very low to the ground...too low... Which test centres will have high ramps and allow me to do just idle?
Thanks!

From my experience, the worst thing you can do is exceed the octane required on these cars. I have yet to talk to anyone that runs more then 91 and actually gets better mileage or has a car that runs better then one on 91 octane only. So, with that said, I would run just that, 91 octane.
Plugs, well, yes, they should be done, but only put platinum's in. Everyone gets caught up in the iridium thing, but these aren't new engines, so from what I've found as well as many other here, is that you get better results from platinum.
Now, how old is your cat-converter? Is it an aftermarket like a Magnaflow? If so, I'd try changing it out to a Walker 3 core cat. See if that makes any difference. Also, how old are your O2 sensors? They might be due for replacement even if they aren't throwing codes.
Finally, what ECU are you running? Where is your timing set? The ZE runs advanced timing, or is supposed to, so if your running the ZE on the ZE ECU, then you need to back the timing off a little to get it to lean out a bit. If your still on the original stock ECU, then I'd suggest playing with the car's timing a little (in this case you might want to advance it a little for the correct burn). Also remember that you have no EGR now, so your intake manifold will get excessive amounts of blow-by oil into its streams. You may want to run seafoam through the vacuum system only just to curb this before your test.
Etests are all a gamble, even on new cars. But like them or not, they show whether your car runs right or not. Just because it starts doesn't mean its running correctly. By doing the required work to make it pass without being registered as a hotrod will reward you with fantastic fuel mileage for years to come. Think of it as an excessive tune up.
