We recommend that 91 octane fuel be used with this reflash.

Notes

Will this affect my warranty?

Any increase in RPM limit is at your own risk. If you suffer engine damage that is related to excessive revs Honda/ Acura will not cover your warranty.

With regard to aftermarket parts, the law is that warranty coverage cannot be denied simply because such parts are present on the vehicle, or have been used. For more details read the Kseries FAQ.

Emissions testing shows no measurable difference from stock.

What if you have modifications?

This program was tuned specifically for a CAI (cold air intake) as they give the best power gains. All future tuning will be done with either the stock or CAI intake.
