Misfire under boost.

Recently I've noticed that when in 3-6th at low RPM when the boost starts to build, the engine will misfire. Any help is greatly appreciated.

there are so many other things you'd need to tell us. What's done to the car etc. If you search, we've had lots of threads about misfiring. Misfiring under boost can be a gapping problem on the plugs, it could be your ICMs, it could be coil packs, which one? who knows... you need VAG com. it can be a vacuum issue meaning you have a boost leak... it can be coolant temp sesnor, it could be 1 million things. fill us in

lol sorry but there are so many things to cause misfiring that you'd need to fill the blanks in....

APR Stage 2+ program, no cats,(pre or after), 710Ns, drop in K&N. Everything else is stock. I have already checked the TB boot and replaced the CTS. I do not have a CEL. Hope this helps.

check your coils... if they are all good check the ignition module....
