Surging with Paxton?

[Jeff_oddo]

Mine felt like fuel being cut from the engine when it was jerking. Odd... next time I'll mash the gas and see if it does it. Last time it was when it was partial throttle rolling into WOT when it happened.

Lund locks them open in his tunes...

Yes lund lock them open,but if u have broken/off vaccum line the the computer is telling them to open but they cant because of no vaccum.Also if linkage is messed up same thing.Just bacause a computer is sending commands does not mean it happen,the whole system has to be operating and i have had the manifold and these imrcs off the car and the design is not that great.My linkage was binding and [MENTION=15798]RockStang[/MENTION] noticed the pass side was bound up.I had bad surging and bucking at part throttle.Might not be ops problem but very easy to check.Especially motor lifted for headers or other work,very easy to damage components of the irmc's.

Also u do make a good point about being locked open,i would think if in the wrong gear and rpm with them being locked open could cause some bucking,since they are usually closed at low rpm for torque.I know they say it doesnt matter when boosted but i know my car is not making much boost at that low of an rpm.
