I brought in my 06 STi looking for it to get tuned and purchasing the Cobb AP. First time Mike tuned my car, he noticed that the Fuel Pressure was droppin drastically. He said it might be that my OEM Fuel Pump is failing, cant keep up. So I set up another appointment to replace the OEM w. the Walboro Pump the following business day. He also noticed my EGT sensor was placed in the wrong spot (downpipe) (I dont wanna flame the shop that installed it lol). After the new pump was installed and EGT placed in the correct place, he tuned it again.

He brought my torque up from 239.4 @4500 RPM to 275.3 @3500 RPM. Will post dyno sheets soon! Just wanted to say that GST's professionalism is great and theyre service is amazing. Ride on Mike. :RockOn - not mine:
