We dyno tested a 2013 Nissan GTR with basic modifications to weigh the benefits of Shell's new URT Advanced unleaded race fuel over 93 Octane. This car had stock turbos with Injector Dynamics 1000cc Injectors,SBD Intake,midpipe,downpipe and a PWJDM exhaust. The Cobb Access port was used for tuning and to change settings for the URT run. Dyno runs were performed on the same day in an effort to remove as many outside variables as possible.
