I can seem to figure this out. I've took care of all of my boost leaks and checks plug and gaped them to .28, cleaned fuel injectors, its a rebuilt engine, I'm now running my 550cc injectors and had this same problem with the 450cc. Coil packs new, rebuilt throttle body, rebuilt turbo, replaced seal on biss screw. My wideband hits 16 while crusing when it surges.
