    Bypass valve

    I'm having bucking issues at light throttle because my small bypass valve is not big enough.

    What is the best bypass valve that is big enough to stop the bucking issues I'm having?

    I have same issue. Steeda said that it's caused by the larger injectors being less precise at low speeds. The guy was in sales, not tech, so take it for what it's worth.
    I've gotten used to it and just disengage the clutch at the first symptom, though that doesn't help you, having an automatic.
    If anyone else has any thoughts on this issue, I'd appreciate your comments.

    I recently bought a 3" pulley to replace the 3.6 on my V2SQ to go from 6-8psi to 9-11, then decided to wait until I get a forged shortblock, as several references stated that the GT's 4.6 2V's pistons won't take the added boost. Maybe I'll do a used 03' cobra block and crank (karkraft.com) with forged or billet rods and pistons @ 8.5 compression, or perhaps one of the new 5.0L stroker modular shortblocks to get more torque. With the V2SQ being centrifugal and so not kicking in till 2500rpm or so, torque at very low rpm (like 5th gear) sucks.

    The bucking I believe has nothing to do with ur bypass valve, I believe the bucking issues come from your cam..
