Greetings friend. I do not know why they say that there are no switches for this model if you have seen that yes, moreover, I think there is a chip that is installed in the same one that your car has and there are some programmable that come with a program and some cables with which you can programs with your personal computers. Now friend my advice is that you try to get all the technical data of the straws that I gave you and others and take them to the mechanic and between the two elejir the best kit. But if you want your truck for competition or something you will have to do other things, such as changing the turbo or replacing it with a super chair or putting double turbo, changing mild sentences, putting titanium rods, machineing the crankshaft to remove weight and enlarge the doll etc ... (never ends) and all this does not do by any mechanic, I made your elijes but I tell you my advice is that the discourse will be consistent with the mechanic that fences the work and tries to be possible, to talk to people to whom the mechanic does similar work, to buy their skills. Greetings and we are in contact ...
