Chuck,
do you have your current ign. numbers posted somewhere? i have been reluctant to mess with ign. settings as i do not know enough about them. i have made sure that i do not have any neg. #'s, but this meant only changing a few of them by 1 deg. i have sr motorsports programing. there are lots of high #'s in the split screen. all the way up in the low 20's. i am running upgraded stock turbos and i am still running them sequentially. i live in Fl. so it gets pretty hot. i have the full compliment of upgrades including a street ported motor with all of the manifolds ported and gasket matched.
by the way, i am the guy that was having the stumble problem with my 1200cc inj. i finaly just fixed it today. i plan on posting the cure in a seperate thread. it seems that a lot of people are having this problem. i tried adjusting lag and the transitions settings and this did not help. it is the inj. overlap settings that need to be changed. i set mine to 4,7,7 from the bottom up. this has to do with how early the secondaries start to fire based on eccentric shaft timing. by increasing the #'s, i guess the inj. starts to fire sooner in the combustion cycle. why the lag setting didn't help, i do not know. maybe this is a larger shift in tiiming. i figured i would mention this since you and carson had helped me try and solve this along time ago. i just got my datalogit and love it for this reason alone. No more stumble
