no it wasn't
the det is caused by incorrect ignition angle at midrange high boost load points
instead of copying our turbosystems steve 4i chip and pasting in tables from old yb chips you should have left the trick ignition table and map alone
you have lost the 3.10 absolute pressure break line and replace it with a 2.82 absolute point
the line you lost contained lower ignition values

Whilst your over all afr values may have been correct at the time on the rollers and you may well have heard no det you could well have been mapping the tables at the wrong points due to the weber l8 being speed density
