[wesinlessin]

- 02 base rsx
- jdm spec k20 engine/tranny swap
- custom turbo kit, t3 t4 turbo 3" inlet 2" outlet, cast manifold, 2.5 in intercooler piping, fmic, 38mm wastegate, blow off valve, manual boost controller [turned all the way down]
- skunk 2 catback exhaust
- 440 rc injectors
- walbro 255llph fuel pump

right now im using the greedy turbo kit 440 inj cal since it is the closest to my setup and after dirving it around for a while i get an error code; fuel system too lean

i was wanting to know were do i start to get a good safe mild tune with this set up
