Has anyone fitted one of these to their Punto Evo Sporting? I should be coming into a little money due to legal reasons and i'm thinking of spending a small part of it on one of these tuning boxes. Just wondering how much of a difference they make, it takes the 135 bhp up to 162bhp, can you feel the difference? Is it worth the £300?

Is it really worth it when a remap from celtic tuning is £360 and takes it to 170 bhp

I have fitted one on my car and subsequently taken it off due to it causing ECU failure. However, it wasn't a TMC box.

I have one on my grande abarth, I felt like was better option as can be taken off anytime and sold on to get some money back, think they roughly work out the same horsepower give or take,
