Mine hovers around the same 12-14psi range under full load. Sometimes more, sometimes less. Only a few times have I glanced down and seen 15psi or greater, but I was in track mode when observing those higher readings for a split second. The car also burbles and snaps way harder in track/sport modes than when in my mode or v mode with the exhaust setting all the way to track. Something tells me that the boost output may be related to the selected drive mode just like this was. Damn computer on wheels...
Either way, run a few 0-60s and see how you are stacking up against other owners. My summer tires yield a 3.9-4.2 second 0-60 for me with proper heat in the tires on a clean surface. All season rubber launches much harder but doesn't last quite as long if you are pushing the car- 0-60 of 3.7-4.0 on pilot sport 4 AS on custom launch settings with the target RPM slightly lowered to account for the softness of the compound. Let us know how it goes, a 0-60 should highlight any potential lack of power very very quickly. Also, don't flip out if your first times aren't as low initially, it took me a while to get this thing to hook every time. A lot of practice, and tires, went into testing LC out on my car LOLOL.
