Hi Goran. I actually run an Apexi AVC-R EBC to regulate boost but I was told using a preset boost setting IN the wastegate is actually more accurate and gives better response?!?
Anyway, the wastegate has a 0.8 + 0.3bar spring in it, so I can always remove the 0.3bar spring and run at 0.8bar base. Might be a good idea since summer is upon us soon
