Have you run both motors? Just wondering cause I haven't heard from anyone who has. I've seen a few plus 12's and they seems plenty quick. Haven't seen a side-by-side run between a plus 12 car and a 353 car but I just can't imagine that the 353 is significantly faster. Maybe a little but I don't think it's worth the price tag. That's why i'm getting a plus 12. (Most places are out of stock right now and they're waiting for a shipment that's supposed to come at the end of the month). I've also read that the little bit extra you pay for the plus 12 tuned version is worth the money so that's what i'm getting.
