has anyone dynoed with both PHR custom grind cams compared to hks or jun cams on a single turbo. i have a sp63 i'm waiting to put in, and wondering which cams would be the best
I've been trying to get some specifics from HKS-USA to no avail. I have also suggested to one of their reps to do such tests to see the differences in the cams. Maybe if enough people requested such info, they would do so...
