FiTech fuel injection issues

    I had my Cutlass switched over to Fitech fuel injection, and now my LeSabre wagon. In both cases, the gas pedal is hard to push. Then, all of a sudden, it goes past that point and then you're going places. It makes taking off smoothly from a stop almost impossible. Anyone else had similar issues?

    Yes.
    It is "better" of you use the "high" mount for the throttle. Better moment, longer throw and easier to control

    I have the 2x4 and it was a real problem before I changed mount points.

    First I tried the #1, then went to the #2.
    You will need the bushing/stud.

    Trunkmonkey is on the money. Additional throttle return springs are not necessary either unless you are racing and the tech insists.

    We removed the additional throttle spring and now it works MUCH better. Thanks for the input!

    WOW! What a short thread, must not be much issues at all with these FI systems? So far I think I'm sold on buying at least one.

    I have the FiTech unit on 3 cars now. So far they have all been trouble-free and a big improvement in many ways over a carb.

    I was going to try an FI Tech on my next engine. A friend said I should look at the Holley version instead. Any thoughts on the Holley set up?

    Heard nothing but good about them. If I had to do it over again, that's how I'd go. I called fitech over 10 times and emailed (politely) multiple times before they got back to me over a month later to try and help. I've got a couple grand in parts I didn't need attempting to fix issues on my own because they wouldn't contact me.

    Damn!
    The guy that kinda sent me in that direction is an Engineer at my work place. This kid is unreal. He designed a set of heads for his Cleveland engine and had them made. I mean, who does that. lol
    For a young guy he really seems to know his stuff, so I was shocked when he said FI Tech was not the route to go. Looks like Holley for me.

    My son and I put a Holley Sniper system on his '79 Regal with a Buick 350 a few weeks ago. Starts up and runs great so far with no issues.
