Yes, I've had a good amount of experience with tunes in the past. Some of my prior cars include:
2007 BMW 335i with Dinan stage 1 tune
2007 BMW 335i with JB4 tune, Intercooler, downpipe, BOV, Methanol Kit
2014 BMW 335i with JB4 tune
2015 BMW X3 V6 with Burger N55 stage 1 tune
2016 BMW X1 with Custom Tune
Dinan is always a pricey option but they usually back up the factory warranty. Not so much on the current Dinantronics tune. The Burger tunes have always been impressive....good value and impressive performance. This is my first custom tune and I'm so far loving it. The shop I went to did a tune on a mini that shares the same motor. Looks like an increase to the wheels of 59 hp and 47 TQ. I've attached the Dyno graph.
