4 lb lower, shorty headers, boost bypass, ftvb, home ported supercharger, cold air, upgraded maf meter. Does anyone have any tips for a mild street tune. My tuner was thinking 15-17 degrees of timing, reducing torque reduction in the tune to 10 percent instead of 20 percent. Leave shift points stock. I am thinking 11.4-11.8 air to fuel. He said he runs as much as 17 degrees on a street tune. Is 17 degrees to aggressive on a street tune if you run 93 octane with a safe air to fuel? any other tips would be appreciated
