    Any pics? This might help with the bog feeling off the line, when half throttle.

    I went to buy one an it was already out of stock. Always just my luck, but I would love to hear feedback on these. Also, I'm using a throttle lever extension to make my pedal softer. Will this progressive linkage make the pedal softer also, so I can get rid of the lever extension?

    RPnova, I would recommend that you leave the extension in place and see the difference in feel. It is a little bit lighter at first by virtue of the fact that you're only pressing against the primary spring and not the secondary. But having both isn't necessarily a bad thing. And yes, the demand for this took us a bit by surprise. We have purchased every bit of available stock on these and expect to have more in the next few days, so we'll fill back orders asap. :-)

    Hi. I bought on 05/14/18 and I'm waiting for the install and test the Sniper Progressive Linkage Kit (Fixed or Adjustable) option. On the website, I do not see tracking number to match. Thanks.

    I just fitted the Holley part to make my Sniper. It open the fronts first, opens rears at 41%. I set the handheld as to directions, set it to 41%. The problem I'm having is the front two venturis are getting a bucket load of petrol at idle? I disabled the setting and it's trickling in like it use to. Any hints or tips to why it does that once you enable TBI linkage? My AFR is set to 14.2 at idle.

    What is your actual AFR at idle with the linkage enabled?
