Bogging down / holding back on full throttle

[akyakapotter]

As above was having a bit of a spirited drive to work this morning. (EVO in front of me's fault) Noticed on half throttle it would fly along but as soon as I put my toe right to the floor it was bogging down / holding back any ideas on this ?? Thanks nick

First thing I would check would be the ignition system, when did it last have a service? When was the last time the plugs, rotor arm, cap replaced?
Have you got a boost gauge? What was that reading at and what is your boost set to?

I changed the plugs couple of months ago. Not sure on the rota arm ect ive not changed them so been over a year. Its set to 1bar of boost mate slight creep due to cracked wastegate.
