Just put the Interceptor on last night, took me forever to find the plug in. The picture at Tones site helped a lot. I was looking at the pic and underneath the car and found where it was supposed to be, but my car was REALLY dirty and it was invisible to me until my brother reached up in there and played with it a little. Anyway after I found it it only took about a 1/2 hour to 45 min making sure everything was zip tied up. First impression is that I like it! It switches gears much quicker than before, every once in a while I get a hard shift but not that bad. Going out this Sunday and will be posting times. I am running about 25% pressure and 100% delay. I will take a guess and say that it will run a 16.5 to 16.4 with Mickey Thompsons and speaker box. For racing how high should I turn it up?
