A good measure of the effect of heat on performance seems to be top speed on a road course... I run my 100% stock ZLE on warm days (90+ F) at Auto Club Speedway and Buttonwillow and I've noticed no noticeable loss in top speed at the end of straightaways even 10 minutes ~5 laps into a session. Lap after lap at ACS I hit the same top speed of ~160 MPH at the end of the long front straight before entering Turn 1-2, the stock blower and cooling system seem to hold up very well, never had any codes.
