are you manually shifting the car or letting the car shift by itself in sport mode?

if you are manually shifting the car then you need to let the car rev to a higher RPM before shifting the car so that you are still in at a high enough RPM when you engage the next the gear. If you "short shift" the car you won't be in a high enough power band to spool the turbo.
