I have replaced the opti spark with a msd pro billet and also added a delteq sytem.It has new fuel injectors and new fuel filter.The plugs are also brand new and I need help because Im losing my mind over this.
when you got new injectors what was operating pressure ? you need to check fuel press think low or not enough volumme or flow to press regulatorr also check plug gap think gap is not wide enough or you are at rev limit if you are trying to run with cat it may be limiting you advance and fuel flow most times you need to go duals exhaust and low restiction cats and low restriction mufflers but first check fuel press as most times pump in tank needs to be bigger more volumm go read instructions again
