so heres the prob, i had 550 on and a i guess it was dumping to much fuel, so my mechanic said that it still running rich and the car still wont rev high, i changed the 550 with the stock 450 from a jdm and also the fuel rail and the regulator. the guy i bought it off of told me he burnt out 3 ecus, so the problem was that it wont rev pass a certain rpm level (*low rpms) and that it still dumping a lot of fuel. just to let u know i have a supra twin turbo fuel pump if that can be thr problrm also, but i guess not enough air is goin in. but yeah thanks if u can help me out.
