Had a couple of days to test the DTUK CRD3+ box on my A3 2.0 tdi 150
Performance gains are strong, had no issues with any fault codes or coil lights popping up
Tried all 3 modes and I think I like 2 the best for a steady increase in torque right across the rev range, currently set on P2 with +3 power. Program 3 is nothing nothing nothing then EVERYTHING, not very enjoyable, haven't had a lot of time to test program 1 but i'm pretty sure thats the eco setting
I'm assuming +3 power mode is what gets it up to (or close) to the claimed +50 bhp gains, but I will never be able to tell without a rolling road but it definitely feels much stronger than stock
But yeah the box seems pretty good so far, I like that I can just pop the hood and press a couple of buttons to change the characteristics of the engine so easily
