I also have 16' tech pack with Shelby air scoop. 3 weeks ago I ran at sebring, on second run car went into limp mode 15 minutes into run. after that started shifting at 6000rpm, and was hitting temp of 265 at end of run. we had temps 0f 94 first day and 87 second day. Shelby stated they had tested this scoop rigorously, with good results, I tend to disagree. no fun to drive car shifting at 6k, will be adding transmission cooler.
