Hello. I’m new here and I want to start right away, as time is pressing. I want to look at a Zafira A OPC for the next weekend and maybe go shopping. Of course I’ve been rummaging on the Internet for a long time, but you always find Pro’s and Contra’s. My questions: Do the feet, loaders and the LLM from the B OPC plug’n’play? How much PS is it useful to exchange pistons and conrods for better ones? What does a single tuning cost (is that?)? Let Zafira to the tuner or can I drive carefully with the Zafira there? Crammers and loaders a part or separate? Thanks for every meaningful answer.
