I have run Cobb S3 for years, whenever I was not blowing up C39's, very reliable tune for stock turbo. It was the extra juice from S3 that led me to install an LSD, the torque digging out of slow corners revealed the nannies you cannot turn off, LSD cured the problem. Of course, more opportunities to spend more open up once that problem is overcome.
So beware, more torque for low $ can lead to spending big $ to make it most useful.
