It probably just needs to be tuned in the right area. These things are infinitely tunable if you know how. The Sniper is the low end EFI unit and with the software and a computer you can custom tune just about every little thing you would want to. The trick is knowing what and where you want or need to make those adjustments. There is so much you can do I'm sure I'll never completely figure it out. Once I get the major kinks gone I'll probably stop messing with it. There's only one or two small issues that I'm even looking at and I think I know where to go for it so I'm not worried. I justify this whole process as I could have spent half the money on a good carburetor and the other half on a Dyno-tune session. I'm still hoping I'll get both out of this goodie. There's also the issue of RF interference that seems to effect how well things work. I'm not altogether sure how one goes about diagnosing that condition.
I do know one thing...I feel totally ripped off. I got my cable link for the laptop hook up today. 6ft of two puny wires and a usb connection on the other end for $50. Are you serious?? Just because it's from Holley. I think I'm going to start knocking off these things and make a killing. Probably $3 worth of materials in this thing. Kind of sweet and sour though because I also got my new trunk pan for the 67 delivered today too. One year and 5 months till retirement before I'm supposed to be able to start working on it. I don't think I'll be able to hold out that long.
