heres the deal i went from T72 to SP 59, also while replacing the turbo i swapped wastegates. I am running avcr and right now &tuning is a pain in the ass. Around 5400rpm the cars goes from 1.33 to 1.69! However i noticed that if i start from a stop and boost from first to forth seems like it holds at 22lbs.Now if im ridin 5th and down shift to either 3rd or 4th it spikes like crazy and if dont let off it will keep goin! Tried almost everything with the settings with the controller all the way down to 20% duty, boost set at 1.20, 2nd 3rd 4th gears are set at-21%, and even set the feed back to 3 2 2 2 2 & 3 2 1 1 1 & 3 2 5 5 5 still problems,the only thing that could possibly be causing this is the spring in the wastegate??? any ideas let me know!!
