That is correct and I've never had any unusual tuning problems with a single Sniper. The dual Sniper setup that I have doesn't seem to work regardless of what we do. It has been back to Holley for a checkup and we've done everything we know to do. Just waiting to see if a different intake manifold fixes the issues.
