its more so due to the fact that these tunes now have intakes on them. i cant speak for john but i have found from my testing that intakes lean the mixture out thus causing this affect. i have since offered an updated tune prior to me even knowing this thread existed. you can contact mecha on this cause i email him whenever i spend more time on the dyno.
