H22 Turbo setup.

Still running on old tune.
Can't even try to retune, if the boost creep issue isn't fixed....
Hits vtec, boost goes through 14psi....

What Wastegate are you using?
I had a quick read of the initial post and couldn't see it written anywhere.

But i do agree with you that the position the wastegate pipe re-enters the downpipe is very critical.
The longer the better!
I am using a Turbonetics Evolution Wastegate on my setup.
Wastegate pipe re-enters the downpipe after approx 300mm (As long as we could go without hitting the sump/block hahaha)
No boost creep whatsoever.

I have an internal wastgate. Using a KLS adjustable actuator.
At this point the wastgate is not seperate.
It had a seperation before, but I lost it with the turbo upgrade....

Ouch, well hopefully you can 'delete' that internal wastegate, and put the external back on again!
Seems odd that the internal wastegate of said upgraded turbo, cannot keep the boost in check.

No, you misunderstand.
I always had an internal wastegate, but the old turbo exhaust housing had a piece welded to it that seperated the dump from the waste gate.
And that was a t25/28.
Now I have a gt28/71.
Naturally, these build boost more easily than the old turbo. All I have to do is redesign the dump, all will be fine.
This car was never an attempt to build mass power, thats my next build. This was just to build a strong relyable street turbo setup. Getting things working right is more important than building power....

Now i follow =P

And that's the way to do it.. Reliable is the way to go! Power comes second.
I've even considered swapping back to the OEM Engine Mounts, Traction Bar and Flywheel just for a little better driveability.

Well I love my 11lb fly wheel and stage 4 clutch.
And about to fit the after market mounts and traction bar I already have... LOL
I don't care how "racecar" it feels. As long as it never breaks down...

I've got an 8.9lb flywheel.. Haha it's a mean son of a bitch.
I have ESP Mounts and Tractionbar, i like them.. Just don't have anything in your glove box, that way it won't rattle haha.
Good mindset to have!
My tuner has always loved how i've got 3x more power than a stock CB7 Accord, yet it drives just as nicely.
