Yes. You will be a lift pump.
Drive over to see Brad at Calvins Trans in Louisiana, he'll take good care of you. Trans and tuning are two things that you don't want every neighborhood mechanic touching.
Brad builds the trans in Max'd Out for Rob.
As mentioned above...
Lift pump, gauges, exhaust, and built trans.
EGR is nice to have, you can at least do a blocker plate.
Edge Insight CTS is nice for gauges.
Lift Pump I recommend the AirDog2 165, because you can get a lifetime warranty and it has added filtration. Every pump WILL fail, that lifetime warranty WILL pay for itself.
