I replaced the cam follower 3'000 miles ago so hopefully
It is ok.
I am about to spend the day de carboning my valves and change my stock plugs to the NGK BK7E with a .032 gap so I will give everything a really good inspection and test again after. I did recently get a remap done and I am not that confident in it so I think the next stage will be to get it to another TRUSTED tuner
