Red Dot are watford based, they have a rolling road. They will do a call out if required but it will just be a standard remap, no diagnostics and isnt the best option in my opinion.
Perhaps you can call them and they will recommend someone that uses their maps near you?
No you dont need any other mods.
Although I did remove the resonator and fit a GTA intake pipe to the airbox.. very common mod Bob and it only cost £15 for the part!
Makes about 2-3 BHP extra so not much, but the real benefit is when at speed and you want to overtake for example.
