Dang you owned him there. No one has hit 11's just on the C3 pulley and they never will. Yes that's a challenge for you C3 loyals. Don't forget to mix infamil to fill your bottle!!! LMAO.

Remember DA is only to compare your car to another at every incremental measurement on the track. 60', 330', 660', 1000', 1320'...if you don't have drag radials and you can't drive then it's useless. If your never going to hit the track then your only resource is to dyno. That doesn't mean you can't datalog on a lonely stretch of road, and give those results to your tuner and see if you need any tweaking.

Most importantly dyno or datalog on the coldest day available and still safe to run the car all out through 3rd. On that coldest day, not by coincidence will have the lowest DA of the year and will have the thinnest air available. This will be the day your tune will lean if it's going to. If tuned to that air anything warmer than those conditions you will have a completely safe tune barring part failure.
