Alex, can you speculate on why APR or Loba bring more power than Autotech ? My car doesn't run as strong as it should for a stage 3 although logs don't show anything wrong (my Autotech makes 128-135 bar with the RS4 valve). I'm thinking I might have some issues with the LPFP (it makes only 3.2bar at redline) or the HPFP (maybe the right pressure doesn't imply it gives enough fuel ? )
