Tunnel Ram Tune

Ok folks, got this thing running really well now. Super reliable, very responsive and cruises great.
Now because I’m not one to leave things alone. I’m curious as to what it might run like with a pair of 600 mechanical secondary carbs vs the 750’s I’m running now. Keeping in mind this is a street cruiser that gets the occasional beating, what do y’all think I could expect with the swap? I see that FST has a nice looking 600 dp at a reasonable price. It looks to have all the bells and whistles, replaceable bleeds, quick change jet bowls etc. Just tossing it out there. And heck, I’d even consider the vac secondaries.
