    When I changed my fuel pump

    URD thingy says 6 psi but the gauges say 9.

    Stock sized injectors, but with the 7th injector

    Yes, to a walbro 190 when I did the 7th injector

    Is the boost gauge reading from the same source as the URD ecu?

    It's a shitty vato zone one. It's called equius or something. Yes it's from the same source. I'm waiting on money for a gauge pillar with an AEM wideband and boost gauge

    Alright good. I want to make sure which is the actual boost pressure. I have a feeling the autozone one is off.

    A few criticisms. I hate the fact that URD still sells the 190 LPH. They might as well just sell the 255LPH since it allows more room for growth before hitting max duty cycle. Next is more of a question, but are those upgraded OEM injectors which came with the charger, or stock sized injectors

    With a 2.2" pulley? It probably is about 9 psi. I make 7.5 psi on the stock pulley, so that sounds about right.

    Have you considered that the engine is performing exactly as it should? These aren't positive displacement blowers, so expecting massive low end gains might not be realistic.

    I think @Biscuits is talking fuel with 7th and @TRON is talking water/meth. Am I correct here?

    Whoa whoa whoa...throttle back turbo!
    Which supercharger do you have @HamerMan? If it's a TRD then it is positive displacement.

    You are correct regarding what I was asking about.

    Seems like a silly question, but I recently experienced a situation at work where something very similar was set up and there was an uneven distribution which caused a loss of throughput and reliability.

    I agree. I also wish I had the 255 not the 190. And as for injectors, they are the actual stock injectors. I only got one injector for the setup which was the 7th. I toyed around with the idea of pulling the supercharger and putting on the pink top injectors in.
    Yes it is the 1st gen grey blower

    Do you know the factory HP, and the size of your OEM injectors? As well as the size of the 7th injector.

    Factory HP of the 3.4 should be 190 at the crank. Size of the OEM and 7th aren't known. I'm on a road trip to Vegas right now so I can't get the info for you right now lol.

    This post right here is a BIG deal. Excellent find! I will be adding this to the original post thread, as well as to my own truck. I always did feel the stupid filler neck was too big for the blower.
