Nah. I doubt it.  

Mind you, I had an Italjet scooter and that was also restricted.  Only did 25mph, and about 8mph up hills.   took the restricters off and it did 40 up the hills and over 50 on the flat.

Maybe thats why they do a free 1500 mile checkup service...?

Thanks for the technical update Carl.  Any chance you can answer a few other questions?

Do you know if the RX8 has the same 20,000 rich mixture switch as the RX7?

Would a performance air filter/exhaust improve economy?  Whats available?

Hi Bruce,
I do not know if the RX8 has things altered at what service interval but I think that Mazda will have done everything to make the car as economical as possible.
How many miles have you done?
Have you tied cruising at diffrent speeds to see how the MPG varies?Try a steady 3500 on the M/Way(70mph) and let us know.
I would not change anything like the exhaust and inlet as it may invalidate you warranty.
Kind regards
Carl
