i have a 2005 STI with Helix catless TBE DP wrapped, Gruppe-s headers coated, Titek up-pipe coated, AP ver2, 255 fuel pump, GP moto silencer delete, After MAF hose, and a couple of other silicone hoses. so my first tune was all bad since i had a cracked turbo so i got the VF39 warrentyed. I went back today to GST. here are my numbers from the first tune compared to my tune today. base run is my first tune( on right12/6/07) and test run is today 12/20/07 on the left.



so with my new turbo i gained 23.1 whp and 28.4 FT-lbs torque. i can really feel the differance in the power then before when i had the cracked turbo. i am happy with everything that GST(mike and greg) has done for me to get my car to this point.
