It is hard to imagine that that a large injector would provide anything but a rich idle but thats where the reading on injector dynamics website would come in handy.


The ways I mentioned.....
You have a desire for wine on a beer budget. I do suggest a new narrow band, and that could actually take care of things :fingers crossed: but if it does not your either going to need to live with the issue or step up the game with better components.

There is a reason people pay over $200 an hour for tuning on a dyno and its not about squeezing every last hp out of the engine, it is so every issue like this is at least trouble shot and if possible corrected. When something like this is encountered (by me at least) when tuning I can explain what the problem is and back it up with data, and usually fix it or make it better. I have grown to not like any large injector that is not premium although sub 700cc injectors usually are good as long as the brand is at least reputable.

I have grown to dislike cars with 5-0 injectors and refuse to tune cars with deatchwerks. If they are a good denso or jecs 700 and up injector Its possible the idle wont be "perfect"
