For EFI sniper progressive linkage
Alberto A.✓ Verified Purchase•September 3, 2023
Fit perfectly, used it for my EFI sniper for progressive linkage for better throttle response and doesn't take off racing at every light works great
Works great!

Aside from having to crawl into my engine bay to get the old cotter pin off the Sniper, this worked great. Just be sure to update your firmware on older sniper systems and set the progressive value based on when your secondaries engage. Mine was 43%. Also make sure you have 60PSI for your fuel presssure... anything higher will make your sniper sound like a helicopter taking off (since its only using 2 out of the 4 barrels to pump fuel). I had 70PSI on my fuel rail. Installed an external regulator that I could set and helped a ton too.
Easy install but...
ROBERT L. ARMIJO✓ Verified Purchase•August 13, 2023
Easy install, and setup the throttle is much easier to modulate. But there is at times a hesitation from a dead start. Hopefully over-time the Learning app will fix that over-time.
perfect!
