Hi not sure if anyone can help. I have an audi tt bam engine with a stage 2 tune I get over boost of 21psi then drops suddenly to 16psi I have logged maf using vcds (3rd gear pull ) to redline I only get 206gs. I was expecting more with my mods. I have decat and scorpion catback proram filter oversize tip big front mount and forged rods. Is this normal boost behaviour for this type of tune or should I hold higher boost for longer

These small framed turbo's don't make any useful power at or near redline i believe K04 023 holds a bit better boost up top compared to a K03s but definitely not until 7000rpm.

did you check the compressor map for your turbo before deciding on a boost level to use?
