Worth noting I'm running a custom tune with:

- Dinan IC
- Dinan exhaust
- Dinan Turbo
- ER catless Downpipe
- AA Charge Pipe
- XDI-35

On 98RON fuel.
Ambient temp was ~74.5F

Yeah, the bottleneck for IAT cooling in your setup is the Dinan IC—same as I experienced.

That said, when ambient gets even warmer, no IC is going to keep IATs below 110F, which is ideal.

That's why I switched to an Emix tune bc it holds power much better with IATs going all the way up to 155F in my testing.
I don't have access to any better fuel here, unless I mix a few liters of VP racing fuel with my 98RON - if that is recommended?

Can I achieve better IATs with other IC setups? Primarily for such short pulls - not going to track the car very often.
