Abarth 124 Spider Standard and with Bluespark Module

Does tuning module make any difference? Here is Abarth 124 Spider Auto in Sport mode standard acceleration and then with Bluespark Pro Petrol Tuning Module on setting 5. Many runs were performed and all starting from same place, same conditions, similar fuel levels. Manufacturers time for this car is 0-60mph in 6.5s. So we got 0-60mph in 6.47s and with Bluespark 5.97s.
0-100mph standard 16.70s. With Bluespark 14.40s. Bluespark has much better pick-up and less lag.
