F36 440i experiencing timing retardation at wide open throttle.

AngliaGT

I own an F36 440i and have seen that at wide open throttle, my vehicle exhibits a significant lack of acceleration. Current modifications: arm intake, DP, TU HPFP, xHP Stage 3 tune, MHD Stage 2+ E40, and MHD Ecan kit. Engaged in the process of uploading data logs.

Codes?

There are no codes, which is why I am perplexed; while examining the logs, I am only familiar with a few aspects to investigate.

Your IATs are reaching a level that will cause your tune to reduce power to safeguard the engine. What is the condition of the coolant in your secondary expansion tank?

Allow me to examine.
