That is where the advantages of dyno tuning come into play. If there are any problems, you can start the troubleshooting right there. Mikey is a very reputable tuner and would probably be your best bet over a e-tune. Not that there is anything wrong with a e-tune or torqued performance (torqued is great as well). It's just that if your worried about problems arising, you would have an experienced tuner that has probably seen it all right there with the car. For a e-tune, you wont have this luxury and things could get stressful if a problem comes about.
