Default Auto tune vs Dyno tune

I just walked into some money and now i'm looking into tuners. I'm looking at the t-max or the pc-v. Any input would be helpful, thanks...
I have about 2500.00 to spend

You may want to also research this closed-loop system. It's the best IMO:

a big plus 1 on the rev performance unit. works fantastic and you can grow into it without reprogramming every time you change something, and its cheaper than the thundermax

The Rev Performance EMS is the best auto-tuner I have ever used. I have one on my personal bike, and have since installed two more on other bikes. Every one has worked out very well for the application it was put on. Wish I hadn't waited so long to try out this product.

as far as i know auto tune will not change timing,just afr.so yes a dyno might be better,if the tuner knows what he's doing,isn't in a hurry,didn't just get blasted by the manager....

yeah not so sure that this is cheaper than the thundermax at 815 bucks...I run the thundermax and have for over 3 years. It is the best investment I have made on my bike. Cant speak for the other one listed here since I dont have any experience with it. If it works like the thundermax you cant go wrong. But I would save my money on the tuner...i would get a before and after dyno run but not a tune...most indies will do one for less than 50 bucks. But that is if you just want to brag...not needed.
