Just joined the Stratified tune family during the black friday sale. Since this is the first time I've had a car tuned, I have a couple of questions to make sure it's normal or if there is anything that needs to be addressed.
I have a '13 GTI where the only mods so far is the APR Carbonio intake, R8 coils and a step colder plugs from NGK.
I drove the car with the Cobb 1+ tune for a few days while waiting for the custom tune and the car drove great. Once I flashed it with the Stratified tune I can tell that it pulls a lot harder. My questions are
During harder acceleration I can hear what could be described as a fluttering sound, which has me thinking it's the turbo spooling - but wanted to know if anyone else can attest to this.
I have the DSG and opted for the high torque version, and for the majority of the time it shifts amazing still - but ever so often it feels like it either slips in between gears or it will even sometime slam in a gear to the extent that it feels like a jolt. I've even experienced a couple of scenarios where it slipped in gear as i was taking off from a red light. The gear issues have occurred when driving in D, S and manual mode.
Last, which is more of a curious question. I seem to average -3 knock retardation on all cylinders and was wondering whether that is normal/ok or if I should ask for more fine tuned tune.
