Hi guys,bought a forge diverter for my special edition. After a couple of months use, I realised the car was sluggish and boring. Seens I'm running the standard 220 map and a de cat pipe only, I didn't feel the need for the stronger spring (yellow). But thought I would change the spring anyway to see if there was any form of improvement..... Well, well, well.... Massive improvement!!! Lost the flat spot in 2nd, much more responsive and it's way better on fuel. Didn't know if anyone had had this problem or not, so I thought I would share the result. Forge recommend only to fit its been remapped, but the 220 map is obviously enough to require the yellow spring. Hope this solves any issues you maybe having.
Happy driving peeps
