It's amazing that they can get that kind of improvement from the stock programming... if there's no issues with it, then it sounds like all the other s/w downloads are way too conservative (!)

It is quite an astonishment what just engine management software reprogramming can do. Unbelievable! By the way I see in your signature that you drive ( or u drove ?) an Autobianchi A112 Abarth. That was quite a little 'bomb' . I rebuilt one with a friend (a 1979 model) and raced with it ('courses de cotes') in the French Pyrenees montains back in my university years looong ago.

We still have the A112 Abarth. It's my girlfriends weekend toy . It's awesome to drive it, I agree. I use the Integrale (270hp, 1200kg of weight) in the weekends

And what about fuel consumption?
What about the acceleration 0 to 100Km/h? Sensation??
