Part 3: Tune it and Rip it! (Old setup)
If you have no knowledge about tuning, I highly recommend you just purchase a tune. I would suggest RK-Tunes, George Gelashvilli at Gelashvilli Performance, and/or 22RPD. Although it isn't too complicated, one little mistake can cost a lot.
The basic things you want coded are:
1. Have the DME only use 1 narrowband O2 sensor
2. Code out the SAP and EVAP
3. Properly scaled for your larger injectors
VERY Important! On your first start, disconnect your fuel pump and crank the engine over for a bit to get oil flowing to the turbo. You do not want the turbo to run dry at all.
