Ok still playing with a bunch of boost leaks here with the bigger turbo and FMIC, but according to DSMLINK I'm running at ~18/1 A/F pretty much arcross the RPM board? So when I tried to richen it up it to be 11/1 the car bucked, bogged and backfired? Like it was WAY to rich even though DSMLINK says it's right on? WTF? So if I have mega boost leaks I'd be running richer than what was visable to the DSMLINK as I would be leaking post metered air right? So it could make the DSMLINK think so 18/1 A/F reading must run better <with boost leaks,as it's leaking a good part of that 18> than setting it to 11/1 as I'm probably running 8/1 with all the boost leaks? Or is the A/F ratio that DSMLINK gives you gospel directly from the o2 sensor period?

TIA......
