Tuning CPC Module & Losing Burbles
Hi All,

Obtained a custom ECU/TCU/CPC tune which has unlocked it to become a beast, however tuning the CPC has lost the downshift burbles/pops/crackle and it seems it's impossible to get back from a reputable tuner.

Has anyone else got any other Information or experienced this? Have searched forums here and nothing coming up.

I did a stage 1 tune and still have mine just as they were OEM. My tuner also gave me a separate map that pops and crackles a whole lot more but it’s too much so I just run the other map.
