    Rated 5 out of 5 by from 1982 k blazer with a 454 v8 1 ton When I got started I hoped to drag my sweet 454 big block blazer out of the 6 to 7 range with this new system . shocked today I filled up and noted 11.6 miles per gallon not bad but the biggest change is the way in which it runs , it changed the truck . there is a night and day difference in how it starts runs and the highway top end out standing just a little scary . I am on my second fi tech system my ram charger is next and another blazer in the driveway .cant say enough good things as a foot note I live in Colorado so we can go from 5000 ft to 11000 in two hours . I have not wheeled with the system in place but it will be seen this summer in the hills .

    Rated 5 out of 5 by from New life for early Bronco After driving about 100 miles I could not be happier with the installation. FITech kit 30003 provided almost everything needed. I also installed the 40005 in line frame mounted pump. I had to improvise a pump mount to put the pump level with the bottom of the tank. The handheld controller is very cool. Being able to see the air/fuel ratio is such a treat. I've had four different carburetors on this engine and could never find a sweet spot. I am impressed with the value and quality of the kits.

    Rated 5 out of 5 by from Excellent product that's much easier than most. I had mine installed by a professional custom car shop that had done lots of fuel injection conversions. They were impressed with the instructions and the installation. It took them two days to install and tweak the system. The pressure canister works great.

    Rated 5 out of 5 by from Everything Most likely the best aftermarket purchase ever. I am a mechanic by profession and Iput this system on a sand rail it was easy fast and reliable. I plan on buying 4 more love fitech.

    Rated 5 out of 5 by from GREAT EFI especially for the price Installed on a 355 n a 78 Nova, I had all kinds of carb issues rich idle and a big bog. The Fitech has it running like a new car, excellent idle even with my cam and throttle response is instant. I'm beyond happy with this purchase.

    Rated 4 out of 5 by from Make a big difference This was a time consuming install but the instructions were clear and concise. I was able to step through step by step and get it going the first time. It really improved the acceleration a ton. It's smooth and quick response. The only drawback is that the pertronix flamethrower III has an issue on initial start up with rpm fluctuations.

    Rated 4 out of 5 by from FiTech Easy I have had this for about a month. Easy install and bolt on. The display cable is a little short on the ECM wire. I have to hold the cable in as the heat shrink was not done where both cables are the same length. Overall not bad issue, just a nusiance

    Hi i have a chevy 283 stock motor and edelbroke squar bor manifold will this work ok with such a small engine? Also does it need a o2 sensor?

    Asked by: Novalover
    This would be ok to use on your engine. It does use an O2 sensor for operation.

    Will this system work on a 322 buick v8 the intake is modified to take a spread bore carb

    Asked by: Dozee
    This is made to work on a square bore carburetor flange - you will need to use an adapter.

    can I use fitech30003 go street efi 450 hp on a1991 chevy 350 tbi truck could recommend a 4bbl intake im not sure if the fuel pump will supply enough fuel

    Asked by: chevy duce
    yes it will work, all you need is a 350-2104 intake and the fuel pump will support this system on a stock engine.

    After viewing this item I am interested. Question being is will this be applicable to a 1978 dodge truck with a 360 4spd with a thumpr camshaft? Also do I need a high pressure pump or can I use my stock fuel pump?

    Asked by: Lone sheep
    This will work for your application. You will need to add an EFI pump to your fuel system.

    What would I need in addition to the FITech 30003 kit to install this on a 1967 Mustang with a 351 Cleveland?

    Asked by: 67RestoStang
    An intake manifold that has a Holley 4150 flange and a fuel delivery system like their Fuel Command Center would simplify things . There may be more info we need to get all the items so please phone in to a tech @ 800-345-4545 ext. 480 or fill out this form

    Let me ask my question more clearly. I have a Cad with TBI, stock tank pump medium pressure. Won't work with sump, which requires low carb pressure. Can I install a 340LPH high pressure pump (or perhaps 200LPH) in tank, directly in existing pump fixture?

    Asked by: rogersalvin
    I would take a look a this series of pumps - you may need to modify your brackets - Part Number: 027-11569
