I ran with a stock SI in my SE. He gained in 3rd but I hit my rev limiter from 1st to 2nd. We had to shut down because of traffic but he was 1/2 on me. They are only 160hp stock but a lot lighter than a Tour. In exhaust and intake should make 10hp I would guess on both. I don't think an SVT stock will lose to a modded SI. Anyone of of them suckers wanna run send them my way. I'll meet em within reasonable distance. Only if they are mildly modded though. I know of one over in Grand Haven that is neting 202 hp at the wheels! That's with an expensive engine build up though. Toda cams and all the Type-R goodines.
