Default bcs question

ok i have the common boost oscillation, im going to loosen up the wastegate arm a half turn b/c i overboost to like 18 at first then fall to 12-13. im on a stage 2 map so it should be 16-17 , it could be just trying to compensate for the overboost, but if that doesnt fix it...im going to try to clean the bcs and check for the pill, is it ok to run without the pill in? and could i just use a mbc and set it at the appropriate boost level? it seems it would be easier... no boost leaks so far anywhere....i have a small exhaust leak where the header meets the uppipe..i dont think this has anything to do with it though.

stock BCS? Also what are you running for EM? If you can tune yourself (enginuity for example) you would probably be better off tuning boost/wastegate instead of playing with the mechanical stuff.

With the gm bcs you do not need the restrictor pill. You need to reduce your turbo dynamics tables and probably still need to take your max WGDC down a bit as well. In case you didn't already, with the gm bcs you need to start by reducing the max WGDC table by 20-30%. Also it would help to know what car and mods you have. 32 bit ECU's are quite a bit different than 16 bit.
