Congratulations and welcome to the "SC- Club"!
I had at the beginning exactly the same performance at the same BOOST- Level!
That smells of the original "STILLEN- Software"
My TIP!
If your Tuner works with Ecutek or UpRev and knows the "Z"
there is still some power (+40 to 60HP) upwards.....
BTW: In this forum, there is a lot of information about this kit
Greetings and a good Start into 2016
