I am having the same problem as OP. I used the two original shims and torqued bolt to 20NM. My gaps were uneven after install also. After running it around the block there was nomore gap. The pulley was right up against the clutch. It would make more noise when it is cold, but less or no noise when engine is warmed up. I noticed the springs are not as strong on the EC pulley compared to stock. Been running for around 1000 miles with no problems. Maybe I should contact Eurocharged also. Hopefully we find a solution.
