We will require an IDLE LOG before any driving or tuning. This consists of the car idling either while warming up, or already warm, but it needs to be at least 2 minutes long at full temperature (~180-200*F on most cars). Then rev the engine to 2500 rpm and hold it there for 5 seconds, and 3500 rpm for 5 seconds in the same log. Once you are finished, email it to us and we will review it before instructing your next step. Though our base maps are usually very accurate, we suggest that you don’t drive the car in the meantime until our tuner reviews the idle log.
