I installed the 9-10 maps and the car's been running perfectly. If anything it seems much smoother which is really nice.
The only thing is that I've noticed that the exhaust is much deeper and louder with more drone. I'm also noticing a lot more heat emanating from underneath the car whenever I get out on the driver's side. I'm assuming that at least the exhaust note change is due to the wastegate position being set to 50% in the new maps rather than 90%. The heat issue too?
Does anyone knowledgeable know the reasoning behind setting the wastegate position to 50% instead of 90% and is there any effect on the performance of the car other than the sound and reduction in wastegate rattle? (I don't have any rattling yet)
