I believe that. They spend more time working on ramp profile than anything else. What I was referring to is the two lobes that 99.9% of 4v modular customers purchase, the Extreme RPM or the Extreme-R series. I'm sure Comp offers pretty anything you want within the confines of longevity in terms of ramp rates.

Sounds good. Do you forsee any longevity issues for a daily driver or would this be considered more of a "race" profile best used for limited duty?
