Sooooo I recently installed the Sniper EFI on my fresh 360 and to help with the power management I added a progressive fixed linkage. I followed directions and adjusted the secondary % on the lcd screen to 41 which is when I saw the secondaries open. Now I have a popping sound like a small backfire which sounds like it’s in the mufflers. I have shifted the secondary % in different directions with no change. Any ideas, otherwise it’s removing the linkage and back to stock?
Thanks
Keith
