yepyep, we test car in dyno and car run ok, but go lean after 0.8 bar boost


Tuner recomended that i have to change fuel pump for more powerful and injectors.
I know bosch hi power fuelpumps, but where can i found some injectors for my rst, more fuel than original
At 15 psi boost car make 190 ps or something, but very lean.
