We recently finished this 2013 GT-R that got a Flex Fuel upgrade. The result was 553awhp and 671Nm on E85. We tested it back in January when it was stock. Then it had 425awhp. We also ran it earlier this summer when we upgraded it to Stage 2. Then it had 486awhp on 98 octane. If you think your GT-R need more power, just let us know and we´ll help you out.
