That (Censored by Chris) is saying afterburn is killing his turbos, just means he has not figured out why his turbine wheels are failing yet. We already know why all the 9 Blade TDO4HL turbines industry-wide are failing because well we paid to have composition testing done, as well as X-ray, and vibration testing.
The burble tunes while dumb, and ricey as hell, are not doing anything to destroy turbos on decel. Careful what you believe people....
