Early Wrx issue,
Question for the technical guys i'll start with the car,
1994 wrx (import) Td05 model.
Car is runing a Arc Tmic, Full 3inch decatted system using the twin pipe down pipe, Hks panel filter, and a Z4 ecu,new coil packs
Other than this as stock as they come. car is hitting 0.9-1bar off boost everytime, the car is in great shape and singing as it should, but seems to feel a tad flat between 4-5500rpm, feels like its not pulling enough, it comes on boost very well and spools as it should but high rpm feels weak, could this be the ecu pulling the timming back? no error codes are being shown,
any surrgestions what to check?
Any advice would be very appricated
Thanks Benji.
