Heat Soak
When repeated hard use causes temperatures to build up faster than the cooling system can dissipate.
Why it matters
Heat soak reduces power, increases knock risk, and can trigger thermal protection. It is the main enemy of repeated track pulls.
What to look for
IAT, coolant, and oil temps all rising across consecutive pulls without recovering to baseline between runs.

When the DME reduces power output because temperatures have exceeded safe thresholds. Manifests as throttle closure or reduced boost target.
