That’s shitty, $0.15 for a sticker vs $3xx (or whatever it costs now) for a new cai, I suppose that’s their motivation. :confused:

And even if there were some kind of surcharge, that would be fine too. My car still has cats and I run e85. Probably runs cleaner than a stock z.

Yup, most good tunes that still maintain the cats actually run as clean or cleaner than stock but I suppose it’s not politically correct to “encourage” souping up cars anymore :shakes head:

Flashing back to stock with uprev would apparently delete the tune forever/require full retuning due to uprev software changes over the years, so the solution is a secondary ECU from eBay with stock tune and one of the fobs reprogrammed to match it. Back to the tuned ECU for track days.
