After being unsatisfied with my box tune, I contacted DynoBrian to see if he would tune my PCM.
We talked, and I eventually bought an HP Tuner, and sent Brian my tune.
From there, he told me the box tune that I had was essentially garbage. Injectors weren't even the correct size...
Got my car dialed in today at DTM with Brian. this thing is a beast and it is still stock motor... with a genV, 2.9, N*, LQ4, headers, and a full intercooler on pump gas
