Been out for a spin earlier and tbh if I hadn't seen it fitted for myself, I would say the dp hasn't been changed. I'm not expecting miracles from the existing map, but I was hoping for a little difference in performance and noise, perhaps the ECU needs to adapt? 
To be fair I noticed the same, no extra power just noise. But I knew it would need a map to enhance it!! It's only on there as is till I decide where to take it for mapping. I wouldn't expect miracles mate the car still thinks the cars standard!
