Sounds reasonably fair to put an end to these inter - tuner squabbles.

Its actually easy enough to guesstimate safe top line timing if its a simple spec though and wouldnt need anyone to risk a poor customers engine with testing which I would simply not do.

What turbo/CR/head ports/cams and injectors are we talking about on this engine, with what target AFR?

I could put up the sort of figures I would expect to see and you can then put up the real ones Danny.
