Well I have had both, email and dyno tunes. Let me say after that I have had good success with both of them, luckily. Let me try to elaborate a little bit. On the first tune that I ever did it was by GPI being the best transmission tune and the safest tune that I ever got. It ended up being a good learning experience with hp tuners at being an email tune. It's a maf only tune though with leaves a little to be desired if you're a perfectionist like me and want to take it further with vve, torque model tuning, and transmission tuning. Which you can't expect that kind of detailed tuning from a large company because of the demand that they receive. I then stuck with hp tuners after the learning curve I received from GPI which was fantastic. But that's where an individual email tuner comes in. So, I sought to find a tuner that could do custom tunes for vve and torque model tuning. After searching through the forums at hp tuners I found a guy that was up to the task. After multiple logs he finally got me on track and got my car running completely different for the better. But, let me tell you this. After the GPI tune, I then went for a dyno tune, and it was good for setting up a max effort tune for timing and maximum amount of horsepower but not so good for idle and drivability. For that I recommend an individual tuner.
