    never heard of them. but you need to request data from them before buying.

    they dont have any data, they tell you to "custom tune" or get dautschwerks from them (that as far as i can see dont provide "proper" data either). i thought these being 25% of the id (or whatever) price, somebody might have figured out how to use them.

    Deatschwerks has good data on their website.
    I use Deatschwerks and Fuel Injector Connection for all my customers cars/trucks. They make it easy with good data.

    Without data, a "custom tune" is difficult to dial in all conditions.

    iv seen other injectors in that price range. how come you have to dish out $1000 every time you need injectors, when with a bit of effort these could surely be made to function? well, maybe not. if it were so simple, the vendors would surely do it themselves. where is the problem? consistency when they just use a pcb drill instead of a sinker?

    If you spend enough time with them and figure out what settings they need to work right.
    but FIC has some 80# for $580 with good data.
    id rather spend a little money for good data vs burning my time trying to figure out injector data.

    They don't have data because they're cheap crappy chinese injectors and they all flow differently. Read reviews on other sites and you'll see people with dead injectors out of the box, injectors that don't inject at idle (some of their injectors have huge deadtimes and just don't work on small pulses), and injectors that fail after a relatively short time. There's a reason that cheap injectors are cheap.

    Nobody ever complains about the price of their new cam or the price of their new supercharger..... but shit, look at the price of those injectors!!!

    I was kinda worried about the same thing, there are a lot of china copies out there. Man, I've just about burned up my 2 injector machines testing these trying to match up sets. While you can match sets for WOT, the lower pulse width differences can't be fixed or even matched so they are saleable. Trash :(
