Hello all, just after some advice really, I be now hit the 1000 mile mark and I told myself once reached I'd be looking to increase performance. Td1 Ect stop me going down the remap route so the warranty safe (ish) option it is. The mtm m-cantronic seems like the most viable option for me as expensive as it is, but I'm hearing great things about the jb1 box more so from the overseas forums. Does anyone have any first hand experience of this box and could share some much needed advice. Thanks in advance.
