As mentioned in the other thread the airbridge ( nothing but cheap plastic and retains heat) and their filter have no mounting and the whole thing flops around putting stress on the coupler to the throttlebody.

The purpose of me going back and looking at 15 spreadsheets of the results above was to see what the gains were and see if plotting 6 Z06s all reacted about the same ( not considering where each car is to elevation, weather and different types of gas) to tune changes.

Clearly as I have always said and proven again you cannot bang a tune out on some chassis dyno, you need to do main tune, drive car a few days for PCM to relearn and adjust and then retest and tweak the tune.
Two of the above did not get that as in 1 owner decided after main tune to put in a CAM and other mods and not get a tweak done and it shows in the results above.
