My car was tuned at ASG and made 289HP (old dyno settings), when a power run was done at Evo-R it made 268HP.

I was there when both WOT power runs were done, no fiddling with settings or changes to the tune were made between runs. That being said, the runs were spaced around 3 months apart (I don't remember the exact details but I believe the original tune was done around July and the power run in October).

The tune from ASG was awesome, did everything I wanted it to and the car ran amazingly - Sean is a great tuner. Warrick is also a great tuner and has many proven results, plus has been more than willing to explain his method and many other aspects of tuning to me. I doubt you'll find many complaints from people who have used either, most of the 'complaints' come from people who haven't even used the tuner.

A number from a dyno is just that, a number, don't get mad because someone says they have 300HP, just go read NASIOC and you'll realise just how stupid the numbers can get.
