To "floor it" when the engine is still cold is extremely hard on every engine while parts are expanding at different rates and oil is still running thick and slow... Especially a Porsche engine with 9qts of oil to get warmed up. The DME also runs a different tuning map during warm up which probably keeps the motor down on power to help protect your engine er... wallet.
Give it a few minutes. When the temp gauge says 180 it's time to play.
