Mustang 2006 Whipple Supercharger HELP!!!

I converted my 06s, manually switched Mustang GT to Whipple Intercooled Supercharger and now look for someone in D who can tune the part or have a SCT X3 or Diablo Tuner with Whipple software on offer. Software available, but can’t be set to vehicle. Can download software, but immobilizer blocks everything else.When I recharge “normal” software, engine starts with Whipple immediately, but runs really fat. Error either in SCT Tuner or my motor control unit does not recognize the tuner, Whipple was previously installed on other cars. In the USA there are a lot of tuning companies that offer either software or SCT tuners with Whipple Tune, but most deliver only within the USA, have contacted in D companies, which I don’t want to mention here, these companies with impressive advertising and websites do not even need to respond to email requests…. At the moment I don’t mind that I am the car n I can drive, it is no convertible weather anyway, but also this winter (hopefully) will be over soon. So, who can help and can give me a RESPONSIBLE and competent contact person in Germany. If the vehicle has to be brought, it may also be BENELUX or in eastern France.
