After I put in the DDP stage 3's I got from piers, under 1000ish rpm, it kinda has a little lope like a gasser with a little cam surge. Get 'er above that and smooth as silk. Could that be from running a little too much timing? Currently at 1.9mm. Kinda odd, cause it never did that before. Any ideas? Thanks!

What size injector washers did you use? Maybe you're spraying outside the piston bowl on one or two cylinders?? Mine is smooth as silk, and I'm sure I'm well above 1.9mm.
