    Injector advice - brand, quality?

    I need bigger injectors, most likely 80lb/850cc, in that range. Everybody's go-to injectors are the ID850s, my tuner is recommending FIC 80lb injectors instead. In doing my standard research I found that there are two companies both called FIC that both make injectors for the V. One is Fuel Injector CONNECTION and the other is Fuel Injector CLINIC. They don't appear to be related to each other, but it was real hard to separate reviews because I never knew which FIC they were talking about. So my questions are:

    1. Does anybody have any experience with FIC injectors?
    2. Which FIC was it, Clinic or Connection?
    3. Are FIC injectors any good? I saw a number of comments referring to the FICs as not being as good as the IDs.
    4. Given that the difference for 80lb injectors is about $400 per set between the IDs and the FICs, would you put FICs in your own car?

    Thanks for any info on this, doing the research on it hasn't been as helpful as I had hoped and I was hoping somebody here had direct experience with them.

    I would use whatever your tuner is suggesting. My tuner loves ID850's and that is what I went with. He claimed the ID's were easier to tune since they give you detailed flow characteristics.

    I agree that you should go with what your tuner recommends. He obviously is more comfortable tuning with the FICs, and at the end of the day, he cannot blame any issues you might have on your not using the recommended injectors. My tuner liked FICs (fuel injector connection) also, so that's what I went with.

    Also, I think you'll generally find that people are referring to Fuel Injector Connection, not Clinic.

    Re: Injector advice - brand, quality?

    I probably will go with what my tuner recommends but I never do anything to my car without doing independent research first. I just wanted to see if anybody here had direct experience. I talked to my tuner again, and he said they actually work with Fuel Injector Clinic, and that their equipment was all upgraded a year or two ago, and they provide flow charts with all their injectors, and they're based on the same Bosch units that ID uses. They're just $400 cheaper, lol. Anyway he's been doing this a long time and their shop has a good reputation, so I'm just going to go with the FICs and trust that they know how to tune to them.

    We have an ASNU injector cleaning and flow matching machine, world of difference between the spray pattern and consistency of the ID's built new to spec and the FIC re-drilled. If you saw the spray pattern there would be no question, go with the ID's...nothing better.

    id injectors are by far the best, not an area to cheap out on. sure the others can be made to run ok, but they are not as consistent.

    Tony at the shop told me the same thing this past Friday when I was there getting tuned. Definitely doing them within the next few weeks.

    How are they "by far the best"?

    Do you mean they make way more power?
    Do you mean they will get noticeably better mileage in the car?
    Do you mean the car will be more responsive once properly tuned with the correct injector data?

    I have seen no discernible differences in these areas amongst a significant sample size of boosted LSx cars.

    There are thousands of people who have used FIC, Siemens, and FAST injectors at half the price of ID's that produced the same hp, drivability, and overall results in the end. I just put a flow matched set (within 1%) of Siemens 60's in my personal 14' A6 V and they still have plenty of duty cycle left at 570rwhp. I plan on installing an LS9 cam and 9.1" lower pulley to get me to 640rwhp and they should still be able to fuel the car since they flow at 74# in the V. Would I use a non-matched set of these in a car? Nope, but proper flow matching gives you a great set of injectors with essentially identical dynamic flow characteristics and spray pattern.

    I thought this pretty well covered it. No conspiracy theories needed. Sometimes better is just better.

    there are so many posts about this topic on different ls forums.....no question that the Injector dynamics are the best.
