You wanna trim a map? Start with a good baseline, then crank the timing up a few degrees in the mid‑RPM range while tightening the jets a smidge. Keep the air‑fuel ratio tight, 12.5 to 13.0. Watch the knock sensor, cut back if you see the hum. Once you hit a sweet spot, lock the injectors on the low‑rev side and push the timing later at high RPM. The key is to keep the torque curve smooth—no spikes or dips. And always test in a real run, not just in the dyno. The real engine will tell you where the tweak needs to sit.
