BoostedGT480
Slow 3v
10 psi is fine. You should put it on the dyno to check the tune and A/F since I don't see a wideband on the dash and see what it's putting to the ground, my guess is 480-500 rhwp SAE. Once you go over that, stuff starts breaking at a much higher frequency. Not to say you can't go above 10psi, just saying there are a lot more failures after 500 rwhp than under, say 450 rwhp.
Its already been tuned. If I remember correctly, it put out around 480. Im planning on building the bottom end to push a little more boost in the future. But for now, Im having plenty of fun in it.
