    ID1050x on early e38

    Given up! can properly tune these cheap injectors I bought!
    So decided to bite the bullet and will get quality injectors, problem is that the ID850 (the best fit) are now discontinued. My E38 is IFR capped at 63.5.
    With double, half,half the ID850 data fits well. The 1050x with larger volume is way way over the max- whats the best solution or proper way to enter this injector data data E38 ?

    on a side note: according to Injector dynamic website, these 1050 injectors will only be at 45% duty at full boost @ 6000 rpm in my setup- is such a large injector still recommended? will it idle, and pick up ok? Sucks to have to pay extra for something that is over engineered (I'll never run anything other than pump gas)-
    -should i just save 400$ and get FIC 850s? (fuel injector clinic).

    Saving money to go with Fuel Injector Clinic injectors or even Deatschwerks injectors would be fine with me if I didn't need the 1050x injector size. Both of those places sell good stuff.

    If you don't post your tune and logs when you have questions you aren't helping yourself.

    Just so you know. I have the injector Id 1050's. I bought a salvage Silverado that had an engine fire. Well, in the fire a few injectors got burnt. The plan was for a turbo and e85, so I had already bought the 1050's. To get the engine up and going I put the 1050's on a bone stock engine. It started and idled like stock. Of course I updated all of the injector data with injector ID info. I also had to scale them.

    Aren't the 1050's a 117# injector at 58psi ? If so, that will fit in the tune with the double stoich method.
