I think the timing is soft across the board, causing it to take longer to recover. Now on the street, it's a completely different story....spools quick and is very lively...but of course there's no vht on the street either.
Whats quick? I see positive pressure low as 2100RPM. Little turbo is almost like the LSA blower I had, touch the gas and its in boost.

That's a lot of weight to move, speed/et calc says that's a 1000hp to move 3750 to 150MPH. Almost same power it says to move my 250lb heavier car to 145MPH. I don't see even the billet 7875 hitting that number.

I don't have any hard data on the spool time. But there's no painful lag like what I see at the track in 1st gear. How much power are you making? Hp and torque.

Never dynoed mine. You know what your timing is at? Playing with timing makes a pretty good difference in spool time.

I've yet to look at the tune file. Only thing I know for sure is, at max boost 21psi.
..it's 14 degrees.

If it's built, do you think you'll ever consider upping to a t6 bad boy turbo? (After you max your current one out of course)
Now that you're steering towards an automatic that is.

Eh, I dunno. That would open up a whole new can of worms, as in moving the radiator...as well as new exhaust. I'm thinking this single 3 inch would turn into a rev limiter. I also still don't have a welding machine to make it all happen either....or the cash. So with that said...it's gonna be a while.

I can't help but to agree. I'm sure this tune is holding me back quite a bit. But over the past several months, I've spent quite a bit of money on the car. Rebuilt the motor, new turbo, tires all the way around, and some other things I'm sure I'm forgetting. It will come through.
