im not sure if i have the lag or not but here is a symptom that i would like 2 share with u guys. like just going through the gears, i get on it below 5000 rpms and it kind of studders but not like the lag problem at 5500. it studders and u can hear the intakes real good. it doesnt lag, it still gets up fast its just under 5000 rpms. maybe this example will help more. it feels like if u were driving a manual car and were in 6th gear and get on it. it feels like you need to downshift. is that a lag problem or normal. in other words, its not too smooth. wondering if it has to do with the ycci or ycct??
