These are the optional "The Nutty Professor" +275 RWHP and +310 RWHP race tunes. These tunes will not defuel! This option may be added for an additional cost of $300 for the +250 RWHP and $400 for the +275 RWHP.
These are the files that seperate the men from the boys! If you want to make heads roll and winning the race is your most critical goal.... Go Nutty!
