Hello together, I am currently thinking about buying or having a chip for my 225 TT. I would like to have this increase in performance entered in the papers. However, the offer of ABT or Wendeland with a good 1300,- is too expensive for me. Can you please call me other trustful chip tuners with good price performance ratio? Please calmly all opinions incl.: – Price incl. installation and TÜV registration – Performance data – own experience Thank you already
