Just curious
CobraBob said:Unless you get a tune, the numbers with intake and exhaust mods are going to vary quite a bit, since the stock numbers are known to vary from 340rwhp to 395rwhp. Don't expect 420ish rwhp with stock tune, exhaust and intake. In my case, my stock horsepower was 363, and with intake and exhaust (catback and catted midpipe) I made 388rwhp if my memory is right. It wasn't until I got a tune that the motor really woke up. So the numbers posted here should specify whether they're with the stock tune or a custom tune.
