Converter slippage numbers can be missleading under certain circumstances. For example, if you at the top of the gear and the car is out of breath, the efficiency numbers will be unuasully high. I would bet your not accelerating near the trap, or way out of gear.

Edit: I am running a PTC converter in a turbo application and hope to get around %4 slippage. This is bassed on similar combinations running the same converter and considered to be extreamly good.
