You activate your burst (yellow) NOS by tapping 'A', holding 'A' uses your regular (blue) NOSPosted by Doc Buddha on 01 Dec 22 at 13:03 ThxPosted by beastman rules on 27 Dec 22 at 19:37 This achievement is bugged for me. I've used max burst nitro basically in every story event and I just finished The.Grand.Posted by Jddev on 21 Aug 23 at 14:19 ^ Restart your game and try it again.If you don’t feel like you’ll hit 5 in one race, you can restart as it’ll still count the ones you’ve previously got rather than attempting to get this in multiple races.Posted by Ox1893 on 21 Jan at 01:20 Leave a comment
