Hey all! Well summer is approaching (read here for some) and with it comes better fuel. I know my car sure seems to gain seat of the pants HP in the winter when the temps are cooler, in the winter months. I have always attributed that to the colder IAT2 temps, it routinely hits a max of maybe 100* tops and cruising is in 70-80's in the winter. In the summer on hot days like today it is running 130-135 cruising and over 160 sitting at idle.
I had my car tuned in cooler temps as that happened to be when I bought it and was getting tuned and I think it shows in how it runs, it is just a rocket in sport mode during the winter. However I never had a tune done in the summer months which leads me to my question.
Is it worth it to have a summer tune? Is the quality of fuel so much better in the summer that with a tune will offset the huge temp increase and put out more power than a winter tune running summer fuel?
