MBC+A issues/questions

I have been having a couple of issues with the mbc+a set up. I have recently installed the Viggen IC so since then a few things have crept up. Like getting a fuel cut 5 weeks after installing the IC and in warmer weather 34C.
So I started from scratch to set up the mbc+a last night,
1. I closed off the anticipator.
2. Adjusted the mbc until I got fuel cut.
3. Backed off the mbc and did runs with no fuel cut. So ok.
4. Started to open up the anticipator.
5. (anticipator) at 1 3/4 turns the boost was 1/2 way on red and stayed there. At 2 full turns the boost was 1/2 in red but settled back to start of red. At 2 1/4 turns the boost was only to start of red. Q? The optimum setting is the one with the boost staying in 1/2 into the red even at high rpms? If boost drops to start of red, this is not good. Am I correct???
6. On one of the runs with 2 turns I got fuel cut in 2nd & 3rd gear!! wtf?
7. So I backed off the mbc just a hair.
8. Seemed to be fine after and I have been doing this for an hour so I went home.
9. This morning I set the anticipator back to the "1 3/4 turns position" to try and hold more boost. I was not even able to get in the red!!!
10. I then set it back to where it was at 2 turns, and it boosted 1/2 way in the red. What's going on here???
11. Just shaking my head here at work. help!

Any advice on set up. Am I missing something?

about 2 hours ago i got home adn installed it
and heres my review
THe device installed extremely easy except that i could not remove the wg hose formt he bpc to use the smaller hose to loop the wg to th turbo.. instead i used the hoses already there.. would this make a difference. Anyways first run noticed red ont he left hand side of the needle for the first time ever. but spool wasnt great. . twisted the apr a bit and finally got it to go about 1/4 red and spool quickly... I didnt notice a reduce in lag off of the line though.. it still seemed to take its time.. im waiting to take a colder run though tonight

Its sitting at almost fully on the mbc and about 1 1/2 to two turns on the apr... IM thinking the reason that i am not seeing half into the red is because or my stock filter/box and dirty filter. i also have a return flow ic aka 99 9-3 ...

I would appreciate some comments or suggestions
