Did you mess with the settings? If it is the original Drag it should have an adjustable vaping curve feature that you can set to hit harder when you first fire the mod and then taper off to your desired wattage (or temperature, if vaping in TC). It is adjustable over the first nine seconds, in .5-second intervals.
So, let's say you vape at 80w, and you want a faster ramp time. You can set the mod to hit at 120w for the first couple of seconds and then go to 80w for the next 8 seconds, at which point the mod should time out.
