After it's been cleaned up a bit it looks as though your engine is missing a bit in the higher rpm.
Whats your timing set at? how much timing retard are your running @ full boost? how much boost are you running?
Your afr looks like it could still be cleaned up a bit.
Whats your base timing set at?
Whats the rest of your set-up?
Vital info.
T3 .42/.48 50 trim
Stock ignition, new plugs 2 step colder gapped to .030. Cap and rotor do look a bit chewed up.
Timing is stock, with boost retard feature on Uberdata. We attemped to retard and advance the ignition timing several degrees and got no power from it.
