Just got my TTS Tuner today and reading Master Tune guide right now. So far if your familiar with the SERT you pretty much wont see much difference. The tuning tables are almost identical, infact the whole GUI is identical. I haven't gotten into the good stuff yet, Data Tune and Master Tune, and wont be ready to load tuning files into my ECM and play for a few weeks. Just got word today my Jim's is shipping out tomorrow so going to hold off and use TTS for my first engine tune for the new motor. My wife, Carrie, managed to Honey Do me into installing hard wood floors through the whole top floor of the house, so i is going to be busy for a few weeks. I knew something was up when Carrie gave in so easy when I begged her for the Jim's

But it is really worth it...
