I would do JWT ecu, a boost controller and pure race gas. I think you have 98 octane for pump gas right? Turn the boost up to 17-18psi and run some sticky tires for your race. You'll be wasting time with AFC if you can't tune it on the dyno. If you can't get JWT ecu in time. you can still run high boost just make sure you have good octane. And listen to the engine carefully under full boost to make sure it doesn't ping.
