What does your pyro say?
IMO the problem is that your wastegate opens up and even though you overpower it a bit you do not get the full boost you should get- I think blocking the wastegate isn't a too good idea, wastegating the turbo to around 30-35 psi is much better.

Even at your elevation, you should be able exceed 30 psi with the Comp on kill.
exactly, install the j hook. its why they gave it to you with the box

While running the boost elbow on mine, I can get upto 45 lbs of boost with the Comp box set on 5X5. I'm starting to think that I need to turn the boost back some. Hopefully that will contain my egts as I can reach 1200 pretty easy on a WOT run down the highway.

I have a question on this... I have a Banks Big Head waste gate and I can't get much past mid 20's without dropping to 3rd. but I don't see a place to use that elbow on my turbo??? I'm I missing some potential power?

well the "j" hook was not in the box, piers just gave it to me, i have heard mixed messages on to install it or not. i was told to not let the boost to go over 33 with my stock turbo. "anyone? is that true?" so i was worried. im green with all this, give me a toyota 4x4 to work on, in a snow storm in the dark with my shorts on, i can fix that. so ill install it. and lets see if the pyro will stay a little lower. it will hit 1400 no problem on hard accell.

Does anybody know much about the Big Head design... I have one on my truck and I'm having a hard time getting that much boost too. What's a "j-hook?" Just the boost elbow they give you?
