Default 04 STi - Agile Tuned Stock Turbo + Meth - 327whp / 371wtq

Well, after nearly five years of ownership, I finally had the opportunity to get my car tuned. I have always read good things about Agile here on Nasioc, so I made an appointment with Agile Auto on Sept 20 and drove in from Morgantown the night before. My appointment was for 2pm and shortly after I arrived my car was in the bay getting ready for the session.

Before the tuning session started, a GM boost solenoid was installed. After the first base run, it was apparent that the Cobb Stage 2 map sucked. The IDC’s were around 110 and it was running as rich as the chart would show. Luckily I don’t drive the car hard very often. We did get some black smoke and Hill wanted to make sure of the health of the motor, so a compression test was done. Compression was good all around, but the plugs were toast. Apparently the smoke was just the carbon burning off from my granny driving habits on my daily commute. So for my cars sake, i'll have to change my driving habits.

On pump 93, without the alcohol, we got 314whp and 328 wtq. I’m using a 50/50 mix of distilled water and denatured alcohol. With the alcohol 327whp and 371wtq were the final numbers. What can I say? I’m completely happy and satisfied on how my car runs now. The car runs so much smoother throughout the entire power band with power everywhere. It’s like a totally different car.

First off, I’d like to thank Hill. His level of knowledge and professionalism is unmatched. He did an excellent job tuning my car and answered any questions I had. I’d also like to thank Artie. He did a great job getting everything set up for the tune and wrenching on my car.
