BAD lag after parts install

BAD lag after parts install
I just got done installing an AMS 3" TBE, eBay 02 housing, Forge Wastegate Actuator, Forge MBC, and an MR bov. Started the car and checked for exhaust leaks and didn't find any but I didn't notice a very annoying rattle coming from the front of the car. I thought maybe the downpipe was hitting somewhere, but it clears everything. I decided to take the car out and see how it runs. 1st and 2nd pull real hard hitting 20psi and holding firm. After that though, I noticed that it doesn't seem to spool until almost 4,000rpm and it takes quite some time for it to get back up to 20psi again.
So after doing a bit of searching, with my rattle issue and my long spool up time, I'm guessing that I have a wastegate issue. When I took off the stock WGA, I forgot to note what position the lever was in on the outside of the hotside. When I installed the Forge WGA, I attached it with the lever pushed all the way towards the driver's side (if looking from the front of the car into the engine bay). Anyone know if I accidentally installed it with the flapper in the open position?
I'll probably just put my stock WGA back on and see if that fixes the issues, but I thought I'd check here and get some more advice.
Thanks Guys

EVOLVEU - Thanks for the info. Although I'm kinda disappointed because I was hoping this was my problem. At least now I know.

Well, I just got back in from the garage and I got the stock WGA put back on. Man, that is such a PITA without removing the radiator. Happy to say the rattle is totally gone but it's almost midnight here and I don't want to wake up the whole neighborhood seeing if the spool is back to normal, if not much improved. I think the root of the problem was simply not having the arm of the Forge unit adjusted properly. When I put the stock WGA back on, I bolted the bracket down first and noticed the arm didn't even reach the peg on the flapper lever. I had to attach the arm first and then pull the unit into place, hold it firm, and thread the bolts through the bracket.
I'm pretty confident this will solve my problem but I'll know for sure on my way to work tomorrow and I'll post up whether all is good.

After driving the car with the stock WGA, everything is back to normal. Spool up time is much faster with the upgraded 02 housing and 3" exhaust. The car sounds awesome and accelerates like a beast. Ultimately I just needed to adjust the Forge unit. So, if I get the ambition to rip everything apart again, the Forge WGA will go back in
Now I just need to give AMS a call and see if I can get in on the January tuning special
