    Rated 5 out of 5 by from Holly TBI Easy to install, only took about 15 mins Very easy to install. Some people had talked about having to bend the EGR bracket but mine was already out of the way. Seems to have added some power over 300 RPM. Much smoother Idell and transition is good as well. I also added the Flowtech Shorty Headers that were a direct fit and seems to have helped also

I STILL HAVE TO DEAL WITH THIS IN TWO YEARS WHEN I HAVE TO SMOG AGAIN. I'LL POBABLY BE BACK TO REFEREE AGAIN.

    Rated 1 out of 5 by from total junk I bought the first one to replace the OEM TBI, it ran extremely rich, as in black smoke and raw fuel from exhaust. I called Holley tech and was told my fuel pressure was too high. Inline pressure gauge installed and fuel pressure was 11 psi as required. per instructions. Called Holley Tech was then told the injectors picked up some trash from the fuel tank. I took the truck to the shop and they attempted to sort it out. After their eval and multiple calls to holley without improvement I called Jegs. I spoke with Jegs, the only solution they had was to try another unit which I had to purchase. when the new unit arrived I took it to the speed shop, they replaced the 1st unit and after installation the butterfly in the 2nd unit sticks open. So $1200 tied up in parts that are not working as advertised, $600 in labor from the speed shop and my truck is still not running right.

    Would this work with a 91 camaro? I just recently installed a 350. 

    Asked by: Kkkkk
    This is made to work in a truck application, but depending on this rest of your engine and ECU this could be made to work.

    Have a 93 Chevy k1500 with 5.7 what would be a good intake manifold to pair with this not building a race car but want a daily driver with balls so any recommendations would be awsome

    Asked by: Squarbear87
    We have a few such as the Edelbrock # 3704.

    I have this throttle body but I'm looking for one to give me more performance, do you have any?

    Asked by: Jonathank92
    This is the most you can do with the TBI setup. You would need to look into a new intake manifold and a different fuel management product.
