I'll be right around where you were power wise (mid 600ish) since I'm still running 10mm head studs and have to keep tq under 550, so I have hope it'll do me well.
Also update.
Went on Monday to pick up the car, and came back without it. They didn't want to fire it up for more than 30 seconds or take the first drive without me there, which ended up wasting me a 5 hour round trip.
Fired the car up and the vband holding the turbo to the manifold had a massive leak (like 17.5-18afr leak). You could stick your hand down by the clamp and feel air gushing out. We repositioned the clamp a few times and tightened it down with no success. The bolt for the clamp probably stretched and wasn't allowing it to completely tighten up and seal.
So...got a few vband clamps from buddies @_Mazdarati and Bryce Williams also sent me one since the two I ordered from summit and jegs ended up being on back order even though they listed them as in stock. Both clamps arrived yesterday. So they'll be swapping out today and trying again.
This time I told em no exceptions, start it up, burp the coolant and take it for a drive (log on AP) do some cruising while varying rpm, engine braking and some low boost pulls. Then report back to me if I should go pick it up on Monday.
Fingers crossed
Glad to help, brother. I am so happy to see that thing running. Nothing but motivation for me, but I just need to spend more money. Please come find me if you're ever up around Metro Detroit, I miss you <3
