Well only problem with comparing is I don't have much of a baseline, at least nothing I've seen for myself. Previous owner said it did ~425whp before the X pipe and catback, but I don't really know how good the tune was, and I 'think' that was through the 4.10's. That said - I probably won't dyno till next year when mnmazda (hopefully) holds another event Unless my curiosity gets the better of me before that lol. Just doesn't make sense to pay a high price when I can go with a group and make it much cheaper. I'm hoping to see ~430-450whp assuming I'll pick up ~5 on the dyno from the gear swap back to 3.73's, and the rest from a good tune + the e85.
