Fuel, tune, too high of cylinder temperatures because of the boost spike maybe.

Although if anything, better flowing headers should have reduced boost while still running lean.
I'm more inclined to believe that if the same pulley was used, the boost gauge was just off if it was reading higher boost than anticipated.
Probably it was just flowing more air, and ran lean, pop goes the motor.
