Manual Boost Controller Question
Ok, so basically I'm trying to install a manual boost controller on my stock turbo. Now, on turbo xs' website they show this turbo set up...
Now thats fine and dandy, but the stock turbo is a little different.
Can someone tell me what "THIS"/Yellow Highlight is and what it does/how it works? Thank you.
Also...would hooking it up like this work...
I haven't a clue.
Thanks again...

You actually want to install it like a Pill Mod. Refer to that thread, then insert your MBC in place of the Pill and Voila 
I see you are tuned tho, this is a waste of time really and not needed! If you want more boost then 22psi that HPT allows, consult a local TF dealer and buy a underlay file, then have your tuner retune over that. MUCH better results and the car will drive WORLDS better.

Yea, you really wasted money on that thing. Im not sure why you would buy that.
With HP alone its easy to get 22psi, it doesn't hold it GREAT but it works just fine. If you want more, get the underlay file and the HP control over boost is a TON better. HP has no control over the Wastegate duty cycle, you hit a max point and thats it. With the TF file, he sets that much higher which makes all of the tables more "potent" and you can achieve anything you desire then. Well worth the money IMHO.

It appears not LOL. And some people try to charge you $300 like a regular tune, so be sure to check!! There is no logging at all, they just flash a file and leave. It also never needs be changed during the tuning session (unless there was an issue w/Vinces file for w/e reason). Your tuner then just keeps tuning as he normally would have. The only time you would need TF stuff again is if you happened to flash to stock, that TF portion will now be gone and can't be brought back with HPT alone

Ok, well I still have my old TF files from Vince on my laptop, the only problem is when I put them to my car my ECM is locked and I can't do anything. Should I just have him send me another that isn't locked or something. Btw thanks for the help, sorry I don't know jack about this.

Do you have the cable?
Unfortunately with the boom of hybrid tunes, he doesnt offer that as a update anymore, its a new tune file. If you have the cable tho, you can just order the file from him, or myself if he won't sell it to you directly for w/e reason.

It's a shame that HPT has not unlocked that table, because they really need to be tuned together. IMO, it is bad practice to rely on the ECU to make massive swings in WG duty cycles to compensate for target load. Likewise, I think it is poor practice to simply crank WGDC to 95%. I prefer to roll off load. If the target loads are significantly lower than 95% would cause, then it has to drastically compensate again.
Fortunately, for my purposes, the stock WGDC tables work fine for me. I'm not trying to get heroic amounts on the top end, on the stock turbo.

Yeah I looked this over last night.. sam my car is tuned hptuners by me. I looked at my logs and my duty cylce maxes over 23lbs becuz,of fuel pressure. I can retune u. If ude like. And do remember u r unning meth. Just in case byt didn't see this so I can work alittle bit . My car has issues after 23 tho. It could be what iambroke had tho. Or the injectoe is out cuz before I got the car it was tuned t 30 pounds via hptuners by dumb ass hahn. I wouldn't mind doing hp/trifecta but I won't deal with.the.emailing bull. But like I said I will tune u for 23-24. Just cuz u have meth.

I'd like my 25psi back. From what I understand, you use the Trifecta just as the base and they HPT over it...so there won't be any emailing back and forth ya know. Just flash a Trifecta tune and we can be on our merry way HPTuning over it...

35psi is actually the limits really lol...
I ran 30psi for about 10k miles without an issue. A GM Tech came on stating that over 24psi on the stock pistons will cause failures. I haven't seen a significant gain in power going over 24-25psi tho on the dyno.
Stop driving your car hard until you get the fuel pressure raised

its not hard to figure out, pull the vac tube going from ur boost solonoid to the wastegate, get a 3 way tree and cut the vac hose that goes directly into ur intake manifold, put in tree, run vac line to boost controler then from boost controler to wastegate. very simple.

I have. Between 3-4kish you can run 30-35 psi but you do need to be back around 20-21 by 6k. Not saying this is the best idea, just saying it CAN do that.
