12. Elevated boost levels require precise tuning. Miss the ignition timing by a degree or two and you can say goodbye to that expensive supercharged stroker. Adam Montague from ST Motorsports was on hand to dial in the air/fuel and timing using Diablosport software. The tune for a stock install is supplied using a hand held tuner (flash device), but the combination of boost, increased displacement, wilder cam timing, and ported heads required extra time on the street and chassis dyno for our application, to ensure ideal air/fuel mixture and timing under all conditions is accurate. It was not possible to use an off-the-shelf tuner.
