Would that be Steffani? That sucks that it broke just before the race. However, it has been my experience that that is exactly when things break, at least for me. I tried for 4 years to get into the FFW...every time it rolled around, I was running great a few weeks before then WHAM! Something would break and I would miss it.
He'll like the C-4 and he should pick up a little performance if he gets the combo right. I've now had a C-4 in two cars and they were great in both cases. Worst I ever did to them was wear out the bands and cracked 2 bellhousings (stock ones).
