A Little ECU Tuning Goes A Long Way

We made another trip up to Street Tuned Motorsports before hitting the track at NYIRP last night. The results were good. We put the STI on the dyno and installed a Hallman Pro Manual Boost Controller. With the Megan Racing 3″ Catless Downpipe and K&N Drop-In filter we were able to get ~265 WHP and ~325 WTQ out of the new motor. Air/Fuel ratios are running right about 11.8:1 under full boost and we are seeing no knock on 93 octane fuel.

The result was a 12.81 second run at 107.1 MPH. Not bad for a stock-turbo, full-body car on pump gas.
