Heatwave and tuned cars?

Does anyone else feel like their car is affected adversley by the heat.

I have catless downpipes, FMIC and stage 2 map but I'm not sure if the outside heat has reduced power noticeably or the new O2 sensor I installed has made the car so smooth it just feels different and is actually going just as fast or quicker.

What do you think?

Iat will be higher, heat soak more easily = less aggressive boost.

Get meth!

It does feel like that. The boost comes on a bit smoother/slower but it still seems to be pretty quick. I think meth may be a step to far at this point. It will probably only be a couple of weeks till winter anyway.

I'm having to get a new water pump fitted today so it has cost me 1,000 in the last week to fix. It's a bit frustrating to spend 1,000 just to get it back in the same way (but working). I would rather spend on mods obviously.
