lovin my new 16 but have problems plz help

[Turbo Monk3y]

well i got my 16g installed perfectly today all done by myself.. ( i feel so proud) and after checking for leaks or anything that could be bad i wanted to test drive it so i go out to a stretch of road and in 1st i take it easy 2nd i give it a little gas i watch my boost gauge and it rises so i push it to 10lbs and im like woah this is cool (dont laugh) and so i go into 3rd and im like time for WOT so i floor it and it goes up to 20 and it wouldve kept going but i let off and i go under my hood and change settings on my MBC (its an ebay model type) so i go for another spin YET again it goes up to 20 but i let off in time but during this run there was so much psi that i had a lower IC pipe blow off so i tightened back up and now IM SO confused cuz ive tried every setting on the MBC .... i hooked the bottom end of the MBC to the T which goes to the BOV and the other end goes straight to the wastegate.... did i hook it up wrong ... can someone help me tune i dont want to blow anything when im so close to actually getting this to work... please help

More than likely you're getting boost creep and need to port the wastegate flapper area and port the hole out. If you hook a straight line from the nipple on your wg actuator to the nipple on your outlet pipe and get more than say 11-12 psi, it's boost creep and time to do some porting....

but i dont understand if boost creep is THAT bad then i would hate to get an exhaust setup... i just dont get y its going that high on my stock crappy exhaust its not even a BIG 16g its not ported or anything its just a normal 16g and i cant control the boost ..... another thing is im using the turbo outlet and it has a small nipple on the end of it AM I soposed to hook something onto that??? i just have it pluged for now???

ok wat if say i wanted to take off my manual boost controller how would i hook up the vacuum lines back up to the boost solenoid restrictor???? cuz on my t25 it had a split going to the wastegate and a little nipple in the compressor housing of the turbo... this i think would benifit me best becuase i could be at stock psi like 10 to 11 right?????

If it is boost creep it will not matter at all. I have the same problem. Even with the mbc off I still hit fuel cut (~20psi). I am going to a 20g soon so I can live with it for now. I will get a external wastegate with my 20g setup.

You are getting this with the stock exhaust still on? I have the same turbo as you and had no problems until I upgraded to 3" exhaust. I ran a 16g on stock everything with no problem.

yes i have stock exhaust/ maybe its the way i hooked up the mbc i didnt use the nipple on the turbo outlet i just pluged it... could that be the problem y my MBC doesnt really regulate boost

You can try disconnecting the MBC, then just run a line from your wastegate to the compressor housing nipple. That will tell you if your problem is boost creep or not.

this happened to me when i changed my stock 2gBOV. i had the controller on backwards. Try flipping it around.

NO you are getting CREEP. Did you get the 34mm flapper mod? I just got a big16g and installed it on my car. I have a VP o2 dump and the 16g has a 34mm flapper mod done to it. I still have a little creep, I choose the 34mm flapper mod over port. But I think its worth it.
