'05 GTO w/ perf. tune want to reduce knock retard

[craiggustin]

My car really liked the cold weather, now that it getting warmer I can feel some reduction in power can I adjust to reduce the amount of knock retard? My preditor has ver. 7 software. What screens will get me to this adjustment?

If you are experiencing KR, use the modify tune menu to alter the tune.

Thanks
