I think any cam design that allows the shorter compression(staying open during part of compression) is going to have 2 issues.

1 it limits power for sure and alot

2 If its just a regrind I'm pretty sure your stock sensors aren't going to know what to do with the odd pulse in the flow or the pressure. I'm willing to bet the avg and ignore. In which case you will burn rich and get worse FE. . .

I'm not trying to be overly negative. If it were at all feasible, i'd do it in a second. Perhaps someone who has done a Metro Xfi economy cam swap can comment. Do you have to reflash the Ecu?
