Problems
![](./images/smilies/spacer.gif)
really lumpy unstable idle
only 281 fw bhp
![](./images/smilies/spacer.gif)
Boost creeps on dyno but ok on road which look like I need larger wastegate pipe or maybe convert to screemer
I have got some data logit capture so will post these up soon
I have changed the injectors back to the 540 but still crappy idle
I now believe the problem is the cams or cam timing, are these cams too aggressive for my build or am I a mile out on the degreeing, should I put the old cams back in and get that set up right first, I cannot see that ignition or fuel would make that much difference
Help please engine bulders
