Add an AEM wideband o2 sensor to the list of things to do. About $170 and easy enough to install. Cheap insurance. The wideband is a more accurate way than the stock o2 sensor to tell whether you are lean or rich. You can then make fueling adjustments through the TT chip to dial in your WOT air-fuel ratio. I use an RJC manual boost controller in the hose going from turbo compressor to wastegate for fine tuning boost.
