I know with previous vehicles that I have owned that the custom email tunes from noteable tuners are almost dead on with not much room for improvement. If you have ever dealt with Johan at Diablosport, you know what I am talking about.
So has anyone actually justified the cost of a dyno session as compared to actual results/gains? Any before/after dyno graphs?
The general consensus I get from having read this message board is that it's worth it if you are trying to squeeze every last bit of performance out, but it's not worth it if you don't track a whole lot. However, I'd let some others weigh in before you take my word for it.
The two times I went to Livernois (20 hours drive):
First time, with my 2010 SHO, the dyno session resulted in no changes at all with the tune I had gotten from them via email.
Second time, with the 2013 SHO, I went there and Dan couldn't get accomplish all he wanted. That was back in May 2013, so he hadn't cracked all the codes at that time.
So, from my experience, it has never been worth the time and money to have the dyno session... But I still had a good time meeting with them and other members/friends at the track meeting, so no regret at all. But all that to say that the emailed tune is usually very close to the best you can get from them and if ever they can improve, they will offer you the update for free anyways...
