Misnomer… No “chips” are replaced. The car was “tuned” which means the engine calibration files have been altered. Replaceable chips, or E-Prom stopped decades ago.
The “chips” being sold these days plug into the OBD2 port and achieve nothing but drain your bank account.
I refueled Saturday, not only do I not know the price difference between grades I don’t even know what the price was of the regular fuel I got. I can’t control it and I have to have it so I worry about other things.
I only know the pricing if I check via the GasBuddy app. In general, I know which stations are the higher priced ones, and which are the lowest-priced ones, but–like you–I don’t really look at the price per gallon when I gas-up.
Yes I know but everyone I hang with still say rechipped. You know the sports anchor famous for saying let’s roll the tape. No tape in a tv studio these days. And I still say I dial a phone too!
