Just paint the tank flat black and be done with it. No way a fuel cell is the best fix. A fuel cell will use an external pump and braided lines front to back which is WAY more money and work than just installing the Walbro and painting the tank.

But it looks so cool with the blue and red lines and the loud and annoying Holley fuel pump hanging down the back of the bumper!
I'll probably paint the factory tank... but it's nice to dream.

Ha...You're failing regardless if you use a holley.

So you don't like Holley products, or just their pumps? I always heard the Holley "Blue" pump was a good one. At least that's what I always called it. Don't know if that's it's actual name or not!

I'm having a couple issues now. Started driving the car around the neighbor hood, and today drove it to the gym, about a 2 mile trip each way. The car runs strong, but any time I lift the pedal it wants to die unless I baby it into idling again. If I come up to a stop light after being into it a little it wants to die, I have to work the break with the left foot and the gas pedal with the right. I've done the base idle reset on the tech pages, and cleaned the IAC. Think it's time for a new IAC and maybe a new TPS?
Other issue is the boost still wants to climb out of control, even after opening the MBC full open. Is there a chance I've got it plumbed backwards or wrong somehow? Should be outlet from the turbo into MBC, then out to the external wastegate? Right? Any suggestions? I can't run past 3k RPM because the boost will climb over 20lbs and not stop until I let off throttle.
Those are really the only 2 things I have left to fix before I register it. Everything else (PIMP, head/cam, better turbo) Are all upgrades as they become available.... hint hint....

Have you checked if your wastegate is working properly? Sounds like it's not even functional.

You need to verify you don't have the lines backwards on the boost controller. You also need to make sure the line going to the gate is on the fitting closer to the header (not on the end) and the one on the end is open to atmosphere, not plugged. Once all of this is verified, you can test it by using an air compressor to supply the line going to the gate 20psi and then making sure the valve is physically opening at that point.

So after fiddling with it a little this morning before work, I noticed one of the silicon hoses going to the MBC was not fitting tight, and it may be leaking boost air before it goes through the valve itself.
On the other issue, what is anyone's opinion on the idle?

Anything show up in a code scan? If not, I'd say it's probably a dirty IAC.

I don't have a code scanner, and about 2 weeks ago I pulled the IAC off and cleaned it thoroughly.

You can unplug the IAC and increase the base idle speed to 900 or so (re-adjust tps accordingly as well) and see if it fixes the problem. It won't idle until warmed up because there is no IAC but it will work fine once warm. If this fixes the problem, you know the cause...

Ordered the 4100 wideband from AEM today, plan to install the 244lph pump this weekend ( i get a 4 day holiday weekend, yaayy!), the boost control issue seems to be under control and all that's left is getting this idle correct. I should be ready for daily driving by Monday, and that'll be that! Until your ecu comes out, then it's time for bigger everything!

Boost problems still. I have the hoses lined correctly, as far as I can tell, and it still will not stop building boost! It's been climbing past 20lbs no matter where I have the MBC set at. I took the adjustment screw all the way out and looked inside it to make sure the ball was in there, it is. Then just put it back in by a few threads and the boost is still out of control. I'll try to make a video of what's going on in there.

I did something bad to the car tonight. Went and got registration done because my wife's car broke and she was having to use my truck for a little while. The car ran great to work and to the store for food at lunch, and on the way home I was about a mile from the house and decided to test the throttle. Car cut out bad and now won't idle. Feels like it's running on 1 cylinder right now. Hopefully it's simple like some spark plugs fouled out...
