-10% Sniper Progressive Linkage Kit (Fixed or Adjustable)

It is almost without fail that Sniper EFI System owners experience a huge boost in performance from their new throttle body.  And sometimes the throttle is just a bit "much".  That's not surpising.  The Sniper throttle body flows a huge 800 CFM and on most V8 engines is just takes a small crack of the throttle to unleash a huge amount of horsepower.  That much horsepower can make starts difficult--especially with manual transmissions and grabby clutches.

Here is your solution.  Using one of these progressive links you can bring your throttle in much more gradually.  Choose from a fixed link (opens the secondaries at about 40% of throttle travel) or an adjust able link (and you can set the secondary point to your liking.

Installing this progressive link requires you to have ECU firmware version 1.1.1 (or later) and Handheld version 1.1.7 (or later.)  You can upgrade your firmware at no cost: The instructions (below) provide steps for checking your firmware version and upgrading if necessary.  However, if you would prefer NOT to figure out how to download the firmware and install it on your SD card then we feel you:  You can buy a Sniper EFI System SD Card with updated firmware here.

UPDATE: Holley made the decision to remove the capability to setup the progressive link using the Handheld when they published handheld firmware version 1.1.33.  It can still be configured using the Sniper software.  Having and being able to use the Sniper Software is a valuable skill, but if it's not one that you want to acquire then you may want to consider using the Sniper Throttle Lever Extension to solve your touchy throttle issues.

Note 1: The fixed link brings the secondary to about 97% of fully open when the primary stops at 100%.  If your engine is making less than 500 horsepower then it will never notice that 3%--the Sniper throttle body is already flowing as much air as your engine can consume.  But if you need that extra 3% of secondary travel, opt for the adjustable linkage.

Note 2: If you are using ported vacuum to advance your distributor then this link is going to render that inoperable. Ported vacuum is vacuum that is present only after the throttle blades are open slightly. Because Holley chose to implement the ported vacuum on the secondaries (instead of the primaries) this progressive link is likely going to put the vacuum advance at a point where it is ineffective. If you're reading this going "Ported WHaaa??" then you can probably just ignore this note.
