Relationship between PAIR valve, Engine Braking and Exhaust Scavenging
So I just blocked in my pair valve mainly to get rid of the pops and bangs in the after run and immediately noticed an increase in engine braking. I have fuel cut disabled in the Ecu.
But I fail to understand how blocking pair affects engine braking, since itís totally on the exhaust side of things.
Since engine braking has increased I am feels a slight jerk in throttle, kind of like a little of snatchiness.
Also does anyone also know about how pair valve blocking affects exhaust scavenging, since there is less air now present in the exhaust due to pair being blocked, I believe there is low air pressure in the headers which I think will suck the exhaust gases out more efficiently, donít know but I may be wrong.
That being said, I feel loss of power and torque in the lower revs
