I'm not 100% sure on that, I can't remember what the recommended flash was for that grind of cams. I think this flash was ok with the 1000 and 1500 grinds and the SRS 30 was for the 2000 and 300 grind cams. This thread may have some more information since he was the one that did the original flashes and the new ones are supposed to be similar from my limited reading about them.
I'm not sure now though the first post in there says you would want the stage 3 flash, but in another post he suggested the stage 2 to someone with the 1000 grind cams. There was also someone that posted saying they had the srs 20 flash with the 1500 grind cams.
