Hey guys im quite a noob so try not to laugh to hard, but basically what i need is some of your opinions or experiences just to guide me through this stage of my mods.
I had a stock r34 gt coupe which was running a rb25de and was automatic, which has now been replaced by a rb25det from a stag which has had a sump conversion, a r34 manual gearbox and all the appropriate wiring and ecu. I have bolted on a Hyrbid Fmic, splitfires, apexi pod, 3 inch tbe system and a shortshifter. I am also getting the fuel pump upgraded to a bosch040 this weekend. Now my mechanic says i should get a nis tune done, because my car didnt have traction control and this is messing up the mapping from the standard ecu. Now my questions are how much power would i have approximately at the moment, and is there anything else that i need to replace other than the fuel pump from the na side of things?
Any help is appreciated, thanks guys
