Could be as never knew cam specs when bought and got a decent stall after how large we had to drill the tb air bleed hole out to stop maxing the iacv out on idle.
Or the fact that you can get up to sixty and take your foot off the throttle and maintain speed most distances of a standard length suburban street. Fair chug at lights to requires a heavy brake foot to maintain position lol.
I’ve done very limited research on LS tuning, but the general consensus is that if the tuner recommends drilling a hole in the throttle blade, you should run away with your cash in hand.
Pushing against the converter can be ironed out in the tune - lower the idle and correct the fuel table. Can also time the end of injection (whether fuel is injected towards an open valve, closed valve etc.). Most tuners tune for WOT and spend no time at all to get driveabilty right.
That cam shouldn’t need a big converter to be friendly on the street. Of course your et will benefit from a high stall and even a stock cam though.
