Looking for cheap tuning box

[Dave]

If you understand why/how the tuning boxes increase the power you would cry.

Ruan once explained this to me, I cant remember exactly how but you gain so much more getting a proper remap for the car. Bang for buck its better to get someone to just do it properly there are many people about now who can do it for 100 quid, a tuning box will cost you something similar but no where near as much power.
