This is an option to get a burble tune created for any Cobb Off The Shelf (OTS) map. We will create a new separate tune with this featured added that you can flash and use. The burble effect is simply some pops or exhaust crackle between shifts or when coasting in gear above 3200 rpms. The effect is not present under this rpm so that you can drive the car without the feature constantly active. If you purchase this OTS Burble tune from us and end up using our E-tuning service to do a custom E-tune later on, we will transfer your burble tune over to the custom E-tune at no extra cost. Burble tunes work best with a decent loud catback exhaust system and an aftermarket downpipe. After purchasing this tune follow the instructions here: https://www.boostedperformancetuning.com/pages/ots-burble-tune
