Yup, mine is boggy in 1st and 2nd gear when temps get above 105*, but it does not do it all the time. The car performs well in 3rd and above even with temps are over 115*. I have an FI 34 row oil cooler and their twin turbo but even with tt I only saw oil temps of 235* in rush hour traffic in Phoenix and it was a 118*. When the car came up to speed, 65mph the temps would fall to 220*. I think a vented hood and a CFS triple pass radiator are in order by next summer.
Also I don't know if it worth messing with the tune when you are talking extreme conditions for a short time unless you are tracking, then you need to do anything you can to get cooling.
