Was wondering if any of you guys had noticed a drop in performance?
My ST has definitely lost Torque, not unexpected given the very hot weather and it small "ish" intercooler.
But curious to know on how it (the high temperatures) might affect the performance of other Puma MHEV's?

Think it's due to less fuel being injected due to warm less dense O2 content. ECU adjusts accordingly, but don't quote me on that.

I've generally noticed a loss of performance as my engine is the same size as a loaf of bread.

I've not noticed a difference with my car, however in this heat I have noticed a loss of performance in myself :)

Same here. I don't think most things like operating in this heat.
