    That's incorrect( you will be wayyyyy yo lean) do not do any further upgrades until you purchase a rrfpr and a afr gauge in which to adjust too and monitor it. Also your gonna need to goto bigger injectors with that charger as well I would run Bosch 48's. don't think do grasshopper

    You need injectors, some way to change fuel pressure, and some way to monitor AFR's or there is just no point in upgrading.

    First of all i believe you have 48# injectors already with your X, second a ET 137 is a wonderful SC , BUT will be severely handicapped with a stock ECU. You will just get to the stock 8040 rpm, torque, and boost limits quicker.

    You WILL be lean with the stock ECU and ET 137 SC, as the ECU is mapped for only 10 psi of boost.

    As others have said, get the RRFPR, AFR monitoring, and ECU reflash to wake that sucker up!

    You're next upgrades should be a vtech flash,bosch 48lb injectors, MTXL (afr system) After you get these if you are not satisfied then go with a bigger charger. Oh and you need to get you're manifold tapped for the O2 sensor. Go ahead and do it right the first time and learn from the rest of us that have made mistakes!
