Benny I think you hit the nail right on the head. I only bought the car in late March, so it hasn't seen a summer yet. I can only sympathize for people living in the warmer states. As my first post suggests, I'm not looking for more power, or I would have bought an F6 or something. Just looking for consistent performance, all day long. Ive been looking at some of the intercoolers mentioned on this site. Some of the cheaper ones like wogcooler and monza can apparently hold 350kw or there abouts, but don't seem to hold that figure time and time again. Since my car is stock, I wonder whether that would be enough. I would assume sticking a larger intercooler would introduce lag. Can anyone with one of the larger intercoolers (nispro, HDi, process west, rapid) etc confirm that? Thanks.
