Ben-
Yup, I've checked timing with a timing light, and ensured the cams are all in the right direction.
I pull ECU codes after every drive I take, I've replaced the knock sensor and torqued it to make sure I didn't get a faulty reading from it being too tight.
I'm thinking I'm just going to have to deal with this at events
