TJM/Dahlback chip&diverters installed today
Randy at TJM was awesome to work with, he turned my ecu around the same day, and had it back to me this morning. So far I am impressed with the 91 octane program. I've been considering the m75k valve upgrade. However, now i'm confused TJM recommended it, yet Achtuning does not. Neither had any great arguement for or against,so I leave it up to all you. Wondering in Seattle. Thanx

Not just the N75-K valve.. whic is faster and smoother reacting..
But the 710N valves should be replaced. My personal preference is the Forge 007 valves.. They are adjustable and I found Spring two deliveres a very smooth..linear power delivery.. "Seat of the pants" verified.
The stock 710's wore out quickly with APR's 93 oct. I know Dahlback is smoother and less boost, but it still may be a good added mod.

casing doubles? dirtbike, BMX, or mtn bike?
I lightly cased a set this weekend on my mtn bike at a Trail Jam at my friends' BMX trails. Realized I had to pump a lot harder on the previous landing than I thought.
BTW, there's nothing scarier than a nose case or even a nose bump - luckily suspension can help a lot!

you don't really need to worry about the N75 valve.
surging usually occurs due to the DV's going, not the N75. The N75 was the culprit on A4's, though with the new N75 valve Audi uses (what is it the "E" part number???) surging is not a problem.
Are you familiar with how the N75 works? Did anyone even explain it?

it converts mechanical signal (boost) to electrical signal....
which then is relayed to the ECU, adjusting wastegate settings. If the valve is malfunctioning, it is reading the boost incorrectly, therefore sending fluctuating signals to the ECU and telling the wastegate to open/close to save the engine from overboost. This creates the "surging" sensation and sometimes throws the engine into limp mode.
