95 TSI Awd.Back fire miss very bad when boost starts to build.

Ok so this is my vesy first post. I'm going to start with a list of mods. 16g turbo, RC 550's, Aem wideband, Safc 2 ,255 fuel pump, Fmic kit, No name fpr, no name bov not recirculated and a hacked maf.
I'm 95% shure I don't have any boost leaks. I can drive the car just fine if I'm very light on the gas. But as soon as give a little gas the car jerks misses and back fire very vilantly. It seems to idle ok but only when richen the fuel mixture to +8. but when I set the fuel trims to where there suppost to be it idle's very lean. When this is happening my wideband is 11.5 to 12.5 and thats under boost.I have my fuel trims set a -20 accros the rpm range for my 550's.
I've already replaced the plugs and wires and checked the timing.This did just happen all of a sudden. Just wondering if anybody had any ideas or lives close with a logger.Thanks.

My car recently did the same thing all of a sudden and I thought the plugs were good but a new properly gapped set did the trick for me. From now on I will keep a spare set in my tool box.
