Success!!
Went out in some decent wind with the base back and had the same problems - hard to get on foil and sudden drops.
Took off the straps and it clicked.
Rode for a couple of hours strapless - perfect.
Look like my feet are about 2" forward of the strap inserts - probably why I would stall out the foil on takeoff.
Anyway I will ride strapless - not a big deal as I ride my wave foil setup strapless and prefer it.
Thanks for all the tips!

Thanks guys!
No weeds where I sail but it sure felt like it.
After some research, my board's mast track is 5cm further forward than the iq board.
Here's what ai said:
"The Reality of the 5 cm Shift
A difference of 5 cm (2 inches)[/b] might seem small on paper, but in hydrofoiling physics, it radically alters how the board balances on the water:
On your Foil 177:[/b] Because the mast track sits 5 cm further forward, placing your mast base in the "middle" of your track pushes your sail’s downward pressure significantly further ahead of the foil's lift center. This is exactly why the board feels incredibly sticky[/b] in 10–12 knots; the rig is physically pinning the long nose down. When you finally break that suction by pumping hard, the board suddenly pivots on a longer lever arm, causing that aggressive pop-and-stall behavior."
Seems to be exactly what I am experiencing so I've jimmy rigged the mast foot back to 104cm so hopefully that will help (I was using a 2 bolt plate so I didn't have much adjustment but I found a single offset mast foot).
I've got wind monday and tuesday so I'll give it another go!

I've just got an IQ Foil foil paired with a SB 177 Foil Board (91 cm wide). 85kg and sail freeride foils (low aspect) all the time.
Riding with a 900 front wing; 255 -2 back wing with a +1 degree shim on a 115+ fuse. Mast rake is approx 1.0 degree (ie if the fuselage is flat the board would be slightly angled up)
First time out today. First with a 6.7 and then 8.0 ezzy cross'. Wind was 12 -13kts with 6.7 and then 8-11 kts with the 8.0.
I had a really hard time getting flying...
When it was windy, the board would semi plane and sometimes pop up but the foil would stall quickly and drop down. Got foiling once but it took alot of boardspeed.
With the 8.0 and lighter winds and could not get it flying. I would pump like crazy in what felt like enough wind only to semi plane along or stall out if the foil rose up.
I was not in the straps but had my front foot beside the front strap and my rear foot centre of the board in front of back strap location.
Tips appreciated...
Move stance back? Both feet in straps for takeoff? Plane the board first & then start to foil? Different rear shim? Mast rake issue?
(my other board I ride strapless, couple of quick pumps and boom you are flying)
Thanks

Does reaching with the 115+ in lightwind (<12kts) result in a more controllable ride vs heavier wind?
