Plus when you say "More powerful" you have to take into account that they are larger vehicles, weigh more, and the minivans also have a lot more cargo space

I know it makes sense to have larger vehicles to be more powerful, I was simply asking as to what made them have slightly higher HP figures over N-Bodies. I was assuming it was being bigger allowed a larger exhaust with less bends, but wanted to see if anyone knew for sure. I'm pretty new to the relatively modern FWD GM's, so I'm just grabbing as much info as I can lol

I've already started on the trans tune for mine, while I wait to get a chance to register it for the road (waiting on parts). I usually take it on little 10-15 minute test drives on the dirt road around the cottage I live in (super isolated with no traffic) and won't make any major changes until I can actually drive it on a paved road and get a good feel for how it runs. So it probably won't be for a couple more weeks anyway.
