Well you didn't ask but I will comment anyway..LOL

I put it up against mine on the track.. Infineon Sports.. not driving for time but for handling and such ( could not get your tranny numbers exact.. no matter what I tried.. ) I ran yours with R3's because I refuse to test anything on R5's.. you can't tell whats really going on and it can mask some issues.. So I would suggest tuning it out on R3's.. R1's or sports..

I think the suspension should be a little softer... yet a HUGE problem with this car and even my tune.. is when you blow the nitrous or full throttle the steering goes away.. You can't hit in the turn which is where you need be quick in a Subaru.. in it quick and early.. so there is a bad point there.. Mine is minimized some because I have done a weight shift.. and I have a different balance in my VCD and LSD settings to help with this. I tried working it out in the suspension if I remember correctly.. but it seemed to just cause more issues and even tailspin in some cases.. took too much away from the stability of the car.. so I used the other areas that I mentioned to help the car.. It also allowed me to have quick fall and rise in output ( which actually may be the difference in the Original Turbo as well.. being that with Stage 3 you get more HP quicker.. which throws the car out of the race line more.. and is better for straighter runs with it..for more acceleration ..Original is a little easier on it..and better for handling ) but when I come up off of the accelerator.. the car will come back into the race line if I want it to..

Brakes need a little work.. with R5's I am throwing the rear around.. don't like that aspect.. trying to carve out a turn is much better is all four wheels are on track.. not to mention it slows you down too much.. I would even it a little..

Anyway try mine out and compare notes.. if you want.. but even the field when you do.. TCS and ASM and Tires..
