[QUOTE="BIG JUICE, post: 1352746, member: 11318"] You running level 3? If so I noticed backpressure will sky rocket if you lean into it at partial throttle. Like upper 40s and up to 55psi. I think I'm going back to level 2. I don't know enough about this engine to assume that's ok. Drive pressure and back pressure were about equal for conversations sake on level 2. The spike to 50psi with boost way down waiting for turbo to spool sounds just like what you describe. [/QUOTE]
