It was great having Jonathan in with his LS1 powered S13 Nissan 240SX drift car. The LS1 swap included some upgrades including Trick Flow heads, cam, headers and FAST intake manifold. We used HPTuners to recalibrate the stock computer on the dyno, with goals of maximizing performance and reliability. Gains of 10+hp were made over the preexisting tune all while making the LS1 safer to drift. Keep an eye out for this car as an up-and-coming performer.
