I bought a Labonte S4 kit but ended up not fitting. Partly because of lack of known / trusted tuners where I am in Germany and also Im not 100% happy with my software as it is, dont want to further complicate things, rather just go for new Mapping 1st. The Apr I have isnt adjustable either to help map to the W/Meth kit
Revo would be well suited to a W/Meth kit
