and upgrade it
Or you can warranty the ECU/program for like $50.00 thru APR and have them flash it for you

It may be sub-optimal, but should still be fine. I've never heard of any of the chip tuners requiring stage2, or stage2+ for a non-race chip?

I have four "slots" on mine(V5.0) & can change the programs through the cruise control. I currently have stock, 91, 93 octane programs and will add the 100 oct next time I pull the ECU. Valet mode can also be added to any of the open slots.
