oh the stock exhaust is probably why its so rich, i had stock headers, into single 2.5 inch cat, muffler and then 2.5 out the back.

yeah ve learn can be a bit fiddly, i had alot of problems with it screwing my idle, so had to upp the minimum rpm settings, also if you have a non heated o2 it might not work real well at low rpms, mabe try setting it to 1600rpm minimum or 2000 and see if it helps.

another way which works pretty well is to use blms and just do some logs while driving and then map the blm table to a histogram and then use that to offset the VE table. you will need to turn ve learn off to do it though.
