i just got qouted for a factory one for my vx holden berlina 5.7L fuel injection system was going to cost me $4200, which in a couple of weeks ill be getting, which yeah, wish the systems these days u would not loose if any power at all.
this duel system im getting if i decided to put my foot down and the rpm hits a certain point it will switch to petrol then when its back under that limit it will switch back to petrol.
also when i booked mine in a guy with his 5.7L monaro is getting the same system as me in his car, but he's getting it done before me.
