Header leak causing spark retard?
I data logged a run last night and saw that I had a bout 5 deg of retard at WOT , the only thing I can think of that may be causing this is a header leak?

anyone think its possible?

Thanks.

TTT for you.

If anyone wants to take a look at the specific logs I can email the original poster's Datamaster logs if it will help diagnose the problem.

it could be thought as false knock, fix your leak either way,

A header leak will definetly cause knock. Get it fixed and datalog again to be sure.
