ECMlink low speed bucking/surging, strong on boost

[henrysan]

I just purchased this car, im new to ecmlink and have been reading over on ecmlink forums/wiki every night. the car drives very strong under boost, but during stop and go driving, mainly after moving from dead stop and after shifting at low speed the car lurches/surges very bad. ive gone through the checklist above, and have included a log. thanks

mods are
50 trim garrett
1000cc pte injectors
aeromotive afpr walbro 255 pump
bbk throttle body
fmic
sd setup
dsmlink v3
plx wideband
stock block, stock head, arp headstuds
slowboy manifold, evo3 o2 housing 3 inch turbo back test pipe exhaust

ok I have a new log with all the values required logged in the sticky. I seem to have fixed the low speed surge, by smoothing out the VE table. low speed driving is much better now. But now I am having lean AFR readings on my wideband gauge during cruising speed in closed loop. the gauge reads 15-18 AFR and the logged values about the same, but the wideband log and gauge read different. how do I richen closed loop during cruising speeds? thanks

so i found what was wrong. the basetipintpsadj was set to a crazy high amount, and the wideband had to be set as linear and voltages adjusted. after changing those values the car drives great now, and my wideband log matches my gauge reading.
