HOw come when my modulator valve comes unhooked,,, it seems to make my stall work,,, but with it hooked up,, i never can seem to get it to stall any,, it has a little bit,,, but its a B&M holeshot 3000,,,( i think, i cant remember what i put in it) it never seems to stall even when i mash the throttle hard.... Ive got a decent amount of low end torque anyway and it dont hook up either,, but its never seems to accually rev to 3000 and then engage,, but it will if the vacuum is off of it,, but only in 2nd and 3rd gear,, Motor is a 383, AFR heads,, 10.1 compression, demon 750, Comp XEHR 288 i think,, edelbrock rpm intake. anyway,,,, just wonderin,, thanks
