So I feel like I'm spooling slow - GT2860RS
I'm pretty sure the car spools way too slowly. I usually don't get to full boost (12.5 LBS) until 5k. Is this normal for my setup?
GT2860RS
BEGI S4 with big intercooler
FM exhaust with high flow cat
What should I expect? I'm petty noobish about the factors that come into play when it comes to spooling. Fill me in?

Manual boost controller. I have a TurboSmart eboost2 controller but i'm not using it.
I have an exhaust leak but not pre turbo? Does this cause issues related to spool?
Its a 2002 1.8 stock head and bottom end. I don't think i have a boost leak because my vac is at about 18-19 and my boost doesn't fall off at all once it's spooled.
Any other info that might help you guys help me? Let me know, thanks.

What is your EMS? Are you controlling VVT? I ask because if you screw up somehow and advance the cam all the time, you will spool VERY late.
I also recommend checking all your charge piping, upper/lower intake manifold bolts, and also your S4-turbo bolts.

you can have plenty of air leaks that can kill spool
Also I had same amount of vacuum at idle 29-31kpa with pre tb leaks and boost wouldn't fall off either, it would just take forever to build up.
with leaks at max boost setting on my MBC I was hitting 200kpa, after leaks pluged not even close to max out on it I'm hitting 220kpa+

Alright so I shot a video. I'm using the turbo XS manual boost controller. Standard BEGI s4 piping. It changes size a couple of times. The intercooler is their number two option - a 65$ upgrade when purchasing the kit. Here is a the clip of 3rd gear full throttle.

I just wanted to be the 7th person to suggest that it's most likely a boost leak. As stated previously, a leak between the turbo and throttle body will not affect idle or drop off boost at high rpms.
When I first turbocharged my car I made the exact same thread, everyone said it was a boost leak so I pressure tested the charge piping. My blow off valve (that came with the BEGI kit) was leaking quite a bit of air. I swapped it out and the problem was gone.
