Hi all, Do any of you have a Mase Engineering ECU flash on your 599? The numbers look quite impressive in both horsepower and torque gains. If so, I would appreciate any comments on drivability and other improvements or issues.
I had mine done about a year ago.Very straightforward process.It is hard to say as to seat of the pants difference. You want to believe you can feel a change. That said the car does run better in my opinion.Smoother off idle, pulls a bit harder.Remember that the feel from 200 hp to 250 hp will be obvious but as it gets higher 620 to 660 or so it gets harder to feel it. I feel it made a great car better. Mike
