P31 vs p30




Pretty sure I'm going with the p31, just not entirely sure about the red calipers. Waiting for info on MY 2011 before pulling the trigger, maybe they'll have an option for p31 w/ silver calipers.

This package doesn't include the +30hp. If you want to know it exactly, just send me your VIN via PN and I can tell you.

besides it reaches that speed extremely fast, now I want to remove it at all and also reprogram the ECU to get these extra horses hehe.
I think the performance will remarcably improve considering here in Argentina premium fuel has 100 octane.

I look forward to the feedback.
Where I live in CA, we use 91 octane. Not fun, but what can you do..?
We choose to run BP "Ultimate" (98) in our '12 P31 C63.
