I just purchased a Backdraft Roush 427 r from a guy in Florida. I live in Colorado, it seems to me like the car is not running right. I have a feeling the altitude has some thing to do with the performance for the engine. Unfortunately I know very little about engines. This has been a dream of mine since I was a kid to own a cobra. Can some one please give me some advice or maybe lead me to a performance tuning shop in the Denver/Aurora area. The Backdraft is absolutely the most amazing piece of machinery I have ever owned. Thanks
