Stalls are overrated, i don't have a problem using stock converter on 2006 VE SSV, cam is 233/238 LIFT 0.612/0.604 113LSA plus it's got big port n polish from Marsh Motorsports NZ, OTR, 25% UD, DiFillipo 1 3/4 Headers, twin 2.5" and performance tune from Eastern Automotive NZ, dyno'd at 328rwkw@6,400rpm and over 900rwnm from 4,500-5,500rpm. It's a daily driver that sits at intersections and lights heaps of times a day and idle is fine, slight surge from cam but it sounds mean and is real fun hopping through slow traffic!
I can stab it from idle (800rpm) and it does lag a bit until 2,800rpm but is hardly noticeable and any faster rev would probably slow me down with wheel spin anyway as it does when it hits 5,000rpm, here's a video of a little squirt through 1st and 2nd in 'Sports Shift' mode (not tiptronic), as you can see wheel spin is the problem not lack of stall converter...
