    I emailed Fastchip and they won't work with them, but didn't say why. Another post said they go out of adjustment? What, the pressure regulator? Are the injectors inconsistent? What else is there that could change. Anybody know whats up? Want to know what to watch out for on mine.

    after talking wit Holley the number one problem is the engine running rich. A majority of the time it is beacuse the person who perchased the unit didn't get one with the right injector selection or they don't have enough motor to need the thing. You can adjust the fuel pressure to help lean or richen you fuel mixture with these. It works very well.

    IMO, unless you are going to a nasty 383 or 400, you can probably get by with a stock one or a bored out 454 unit and stock injectors.

    Unless you already own the Holley, <a target="_blank" href=http://www.TurboCity.com>www.TurboCity.com</a>'s TBI's are the way to go./forums/images/icons/smile.gif

    Have had the holley for a while now on a 350. Want to use it with the 400 small block. Just trying to find out what to watch out for while trying to make it all work together.

    Thanks for any info.
