The initial drive seemed to reveal instantly noticeable new ‘pep,” and smoother overall acceleration. The Miata, already ever-eager to go, just seemed more so…the car seems to have more power across the, board, more accelerator-responsiveness, a smoother acceleration overall, with micro-hesitations or dropouts that sometimes appear, especially when the car is not fully warmed up, seeming to be—gone. Notably, in the 2,000-3500 R.PM range (the weakest torque range of the Miata, compelling enthusiasts to zip around at 4,000-6,000 rpm to get the best performance) is improved in a way that makes one almost forget about it.
