Hello together, I bought a new planer like I find nice wide glide mod. 2011. Sound is of course very modest… So now a few questions on my part: – with another exhaust complete system I have to have another LUFI and control unit (or have it changed)? – if I only change the final bags e.g. SE or the original empty space I have to have a complete program? – Which tuning module is the better (ST, TM, PC) or where are the differences? My friend says that I would definitely have to have a Super Tuner with an exhaust system and if only I change the final bags it will be “better” to install a ST…? Do I find it great if someone knows about it or has gained experience and answers me! Thanks and greetings
