I have worked in the automotive field for many years and had a shop for 12 years now. I have got standalones down to a science and now would like to find a new revenue to start taking from customers who want their vehicle working better. I have been around this forum but never really posted much or done anything. I would really like to get the ball rolling on what I need to do next. I am ready to purchase the software and I have the time to learn. My personal car I am struggling with is a 2014 Mercedes Bluetec ML. The tuner I was working with did okay. I do have a bigger turbo so that makes things even more difficult. I also have all the usual deletes. 1st tune the turbo kept surging and stalling, now the 2nd tune I can tell leaves a lot on the table. I am willing to put in the time and effort to make this run better. Someone help point me in the right direction. I also have a CL65 that I would like to work on at some point.

Should I start with WinOls or what is my best way of going.

Winols

Does Swifttec just do modules to delete stuff?

What should I buy from WinOLS? I did download the demo but cant really do anything? I know I am going to need hardward to readwrite to my MB, what do I need there? Its been so many years to just get enough info to even get started.

Is Dimsport a better option?
