It read 578 at powerfab after the tune and headers, It felt like it was hesitating in rpms i took it back to see why it was hesitating it then only made 558. Got a second opinion at Matts she is really happy now..
Her car doesn't even feel like the same car.. I was running the same setup as you on my M6 ZL1 it made 643, 654 and 659 at Matts.. The lower number was the coldest day lol.. could of been better gas on hotter days or winter blend on cold day to the numbers being off.
Now mines back over there now its to 800 on 93 only haven't got to the E tune yet.

The shop was RK Speed. I must say that I should hvave known better and not had taken it to him but it is what it is and it’s all good now.
