    3B discuss

    Hi!
    I would like to ask few things about my car, which has little modification.
    There is 3B engine, Garrett Airesearch T04 turbo, custom EM, bosch 412 injectors (0280156012), 7A outlet cam, custom IC, other, engine stock, fuel pump stock,IM stock, now i have 1bar overboost, cruising a/f ratio is 14, but with about 1bar boost, a/f ratio is 11-10. Is it safe to engine? ecu is chipped and has vems 300kPa MAP, with stock turbo, my car has 2bar overboost, bus now my WG spring is softer. Can I run more boost with that or I need new fuel pump, like 044.

    Thanks!!!!!
