I think the timing was out, so I tried again today. There was something that I didnt do the last time and thats set the tensioner to max with a 8 mm pin in the hole

I done it today with a 8 mm drill in the hole and set the tension to max, then tightend cam wheels and turned it through 2 times and released tensioner to other hole.
I got it all back on ok and timing seemed ok as I checked with cam locks but it still seems less power at certain revs and it feels as if the tesioner is to tight! The compression seems ok as I checked with my spare car to compare and it seems the same
I hope I get to the bottom of this!
