Hello all together I know it’s been discussed here 1001 times in this forum, but I still haven’t found the right answers to my questions. Have also looked in the search function…… I bought the Forge 006. A blue spring has been supplied, which is already installed. In the tuning kit are another 4 feathers (yellow, green, blue and red) and three washers. So to my questions: 1. Does the blue spring have exactly the same strength as the blue ones in the T uningkit? Feels the same, but the tuning kit has a twist more. Have you already had your own experience here in a post from the forum that the blue spring is supplied with, is designed for less loading pressure than the blue one in the tuning kit? Or a page where this is listed again correctly? 2. I drive a charging pressure of 1.5Bar. Which spring is suitable for this loading pressure? I think the green and yellow F I can forget. So blue or red? Or blue with washers? 3. Then you say which spring you should drive, you have to find out yourself. If that is so, then how. That means:, how can I get out if a spring is too strong or too weak. How is this reflected in driving behaviour? Would I be very happy about some qualified statements.
