F32 Dinan Stage 1 Feel Slow?

I have a 2014 428xi and I have had the dinantronics stage 1 for more than an year. It felt pretty fast and very "torquey" compared to stock. Maybe it is just me but these days I feel as if the car is slower than before. When I am in sport mode, rpm goes from 1900 to 2100 slow cruising speed and when I push more the accel a bit harder, transitions straight to 3000 and up. I used to get a more smooth transition with more torque. Recently, I have had my steering wheel changed and maybe thats what caused the problem (people touching my wires or something)? Can dinan tune become deactivated or something and can coding reset the tune? Anyone has similar experience?

On your smartphone you can download dinantronics app and make sure its on Stage 1 instead of Normal... I doubt that anything to do with your steering wheel could've changed that setting though.

1 - Start by checking if the tune is on and on the correct map
2- Get a boost reader and see what kind of values you are getting

Since Dinan does not have the ability to log, your next step would be to take it to your Dinan rep.

You need to get the numbers off the unit itself. It's on the label.

Thanks I was able to access. So I assume the B is stock and S is stage 1 right? Or is B for boosted and S for stock?

B = Bypass (stock)
S1 = Stage 1
