dont know for sure. but, i have had my mbc set up this way for a long time. i turn the **** to the minus arrow all the way for spring pressure, and then to plus arrow for any additional boost that i want. vacuum line is cheap so its worth a shot.

 

i just run the top one and all the way down is 10psi.

 

Thanks for all the help and support guys.....i really appreciate this

 

i have ur same kit stock motor n i run my wg set up like brett and have always used it like brett....using only the "top" one on the mvs will give u inaccuarate reading n it actually "leaks" from there i know first hand cuz i didnt have enough vaccume line to put on both so i jus put it on the top n the car ran ok but it is so much better after i drove to get vaccume line n put it on both...no disrespect to anybody who runs its dif but for the best n most accurate reading i would run it the way bretts running it. try that out n let us know exactly what happens n possibly u will get better results jus watch ur afrs cuz it may be dif u know

 

Ok so i set it up the way brett and johnny said and time first time i drove the car i saw 10psi with my afr's low to mid 10's. So i went to up the boost and it went down to 8psi....so do i have it on backwards? Which side is the inlet and outlet? Im using a basic TurboXS mbc.

 

switch the two lines on the boost controller around.

 

Oh ok ill try it when i get home....also i did notice when i was tryn to go up in boost that the boost cintroller was leaking air....could it be that the mbc is bad and it giving me a boost leak or its because it could have been on backwards....once i can figure out how to actually have control over the boost im off to the dyno....

 

Damn everubody runs thier mbc lol me included but i thought the same thing when i went on boost n it turns out to b u hear the air going through there soo idk i nvr had probs with it

***UPDATE***........Hey guys. Its been awhile since ive been on. Ive been really busy and with the headaches my car has been giving me, i just left it alone for a little bit and havent touched it. But besides all that, today was a new day. my car showed a lot of progress that made me fall in love with my car again...lol So....first thing, my wastegate only had 3 of the 6 screws that holds the cover where the spring goes. now all 6 are there. Also, when we discussed that i needed to remove my stock air box and fab up an intake.....Rob over at Descendant emailed me about a intake that they are now offering for the turbo kit that gets rid of the stock air box. He offered it to me at a good price. And when i called to order it they did NOT want to honor the price that was given to me. Even when i fowarded the email to them proving the price Rob gave me. They wanted like $50 more. So i decided to go a different route, not because of the money but its the princible. So i went to Advance Auto parts and bought a MAF adapter from Spectre. Part # 8705. and a Spectre air filter. spent about $35. then i took the car for a ride and all i can say is WOW! it was like a different car. the car was boosting in all gears (like it should), turbo was a LOT more responsive. all the boost issues i was having was gone. Oh and as far as the boost controller, i put back my AEM Tru Boost and ran it the way i had it since day 1. and now i had controll of the boost. So now i can finally go get retuned again. Ill probably make an appointment for next week....and ill will post up the final results! thanks for all the help....

 

UPDATE... actually $24.95 more is what you where quoted.

Rob at Descendant remember's this clearly... I offer you the intake for $125 via PM or email which was $24.95 less than the regular price of $149.95 if you wanted to purchase it from me right then & there.

I've often offer these one time offers to many customers here on Scionlife or who call in and if you don't take advantage of it right then & there sorry for you loss.

 

^ sounds like bad business. why not hold to the offer? that just doesnt make sense

 

Not bad business...it was a one time offer. We take 100's of call's a day and try to help everyone we come across. This customer was hustling me for a GOOD DEAL, CHEAPEST PRICE...then says I'll call you right back to order it and over 4 weeks later expects a DIFFERENT sales guy to honor than.

If customer would have contact me directly since I gave him the deal he probably would have gotten it.

CAN'T MAKE EVERYONE HAPPY...WE TRY THOUGH!

For those who are curious here's the Intake system:

 

Actually I was quoted $125 shipped. Then when I called I was told to toward ur email to Kareem. And his exact words " the boss said I can not honor that price. It's going to be $170 shipped. I was not informed that I needed to contact you indirect. But its fine, its not the money its the princible. I work on the retail side myself, and when I quote someone a price I stick to it unless cost goes up. And I doubt that's what happened....

 

i am confused as to how thats not bad business. you offered a price and instead of your sales team trying to work with him you guys chased him away. the result of this was your team didnt make a sale and more then likley lost a customer over the events that transpired. what did Descendant get out of this?

 

Hmmm makes me wonder if yr wg was leakin from not having all of the screws in there either way glad u got the issue resolved

That's what I'm guessing.....

 

where were the bolts?

 

The last shop that had my car to tune it played me big time....told me that my wastegate went bad and that had one to replace it...so I said ok and when I got my car back I noticed that it was a used peice and it only had 3 screws holding it

 

I wld have had them take it apart to c if the diaphram was messed up or if the piston was stuck if none of those then the wg shouldnt b bad...u may also wanna get ur map checked to c if the did a good job with that lol they may be playin u there too u never know plus its always better to be safe them sorry

Ok...I figured everything out....the 2 main things were that my Forge diverter valve didn't have the spring for it....I bought it used and it came with some random spring(which I didn't kno)....also my main vaccum line from my i.m. to my vaccum block was tee-d off to my valve cover....now its boosting like it should, cosistantly and I have boost control.....so this week it is going back on the dyno and ill post pics and possibly a video...thanks again
