Incorrect. The higher octane will retard any knocking from the raised boost levels. You are not adding timing when upping the boost - you are adding more air and some more heat. If you have a map that is fat up top, then adding boost and higher octane will net you some more power. You do not have to be specifically tuned for it to have gains from it.

Semi-right here. Correct a tune for 25psi and higher octane (read - more timing) would work here.

Try Falken Azenis, those tires are preety good for the street. Or the factory yokohama tires work very well.

And when I had it Dynoed by three different dynos I always came up with around 290 horse power at the wheels. And I KNOW that is low, even when i called AMS they were saying that Evo 8's with an exhaust, MBC and a flash are making around 300 to 310 horse power at the wheels. SO i am taking my car to them. I have decided if they say its not right and low on horse power then they can look at it and dyno it and look at the tune. They are very well known and honestly my opinion is AMS and Buschur Racing are the two best when it comes to Evos.
