It's no rocketship, it never will be but the car is capable of a lot more than it was giving, these mods have made huge difference to mine, it feels like the car was asleep and now it's awake and on the ball !
I managed it in 7 and a bit seconds, a good driver could manage 7, I've seen a 159 of the same spec manage it befor. I don't think you could get anymore out of it without forced induction and hhuuggggeee amounts of cash being thrown at it
The prodrive back boxes with the alfatune re map was an excellent combination, the hesitation and low rev jerkiness was gone, power was smooth across the rev range and there whenever you put your foot down, and it had more torque. The pro drive boxes didn't sound that great they were quite boomy because ofbthe resonance chamber, the alfatune exhaust is only a little bit louder but it sounds fantastic, sounds like a proper sports car now
In short it's worth just getting the re map done, it's worth getting pro drive back boxes and re map but the best result is alfatune re map and exhaust.
If you only want to spend money on one, get the re map done
