My '13 won't do it in park it seems.

 

Here's another. New Air Raid filters on my AFE stage 2

So why can some boost in park while others can not, I feel very dumb right now, because I make no boost in park.

 

An awesome wife helps

He has a custom tune. He can do lots of things we normal folk cant

 

I believe stock the PCM limits how much boost can be built. I think it is like 2 psi.

 

Ok, now it's starting to make sense.

 

i hope to have a tune soon

 

Just did this to mine.

I gotta say, on a stock truck it sounds rather wimpy. I only went up the street a couple hundred feet, but I'll keep it for a while to get a better idea long-term.

Maybe I'll do the duck-call after I get bored with this LOL.

Is this normal acceleration? I only hear mine when I let off the throttle during moderate-quick acceleration

 

Just tried this on truck this morning. Not really diggin the sound. Back to stock.

I wonder how the turbosmarts sound in comparison.

 

After driving around a bit more, I think I kinda like it. I'll give it another day or two to see.

Mind as well just swap it out for a real VTA BOV once I upgrade my intercooler.

 

mine seems to be open constantly from acceleration only drove to work maybe im not hearing it right but to me it seems like it opens soon as i touch the pedal

 

Did you hook up the boost/vac tube?

 

the stock tune take for account air is getting recirculated and not dump to atmosphere every time you let off gas and bov vent to atmosphere pcm still command fuel for residual boost this is creating very rich condition 12 to 11:1 if you let off and get back in to it right away look in your mirror for the black smoke .....it made my truck run like **** coming to a stop and threw my short term and long term trim off not the best for fuel millage and the longevity of catalytic converters

 

Nope, you got another issue there. Our trucks use maf and map sensors, meters air entering the engine and venting to atmosphere has no effect on this, no your truck wont run rich...your thinking of a VAF setup (vane airflow meter) now that system would need to be re-circed... maf's do not, if you don't believe me, google it

 

all i did was the hose elimination i believe my diaphram is torn ive ordered a new bov hoping that does the trick

 

Silly question but.... Did you block off the hole in the intake tube where the recirc hose connected to?

 

yeah i did

 

oh and FYI, the way I did it was remove the pipe completely, go to the hardware store and find a replacement rubber foot for a wooden chair (looks like the rubber foot on walking canes for old people too), i forgot the size, but it fits perfect over the bung on the intake, then i just bought a cheap worm gear clamp to secure it on (remember this is pre-turbo so were not pressurized on this part of the intake). I just vent to atm, no hose dangling about and its a really good plug - no issues with truck, this will not effect fuel economy, i wanted it like this because as some of you know the intercooler can get pretty oily and gummed up with our PCV system, i would prefer any air recirculated from the intercooler to be dumped to atm, just for the fact that it probably has some entrained moisture in it, id rather pshhh that out then keep it in, granted where the BOV is mounted its not going to be expelling water or curing the condensation in the intercooler, but any air from that cooler that gets re-circulated i would rather it just be dumped to atmosphere

 

I'm sure the truck would still run fine without you blocking the hole in the intake (Due to map and maf sensors) BUT do not do this, as UNFILTERED air will enter your engine, and thats just plain idiotic, go get a $3 chair foot and plug that sucker up

 

So I did the standard VTA BOV mod that caps the pipe. But I would suggest trying the BOV adapter from boomba racing, essenantially does the same thing but is considerably louder. Plus you don't have a pipe dangling nor do you have an empty hole from where the pipe normally attaches. And for those concerned that it will be too loud/annoying, you only really activate the "pshhhh" when you want to. Unless you are the type that hammers down on the throttle under normal day to day driving conditions.

 

You don't have to leave your hose hanging. You can take it all the way off and buy the rubber chair leg protectors from Home Depot/Lowes to cap the intake.

 

I used the rubber chair foot to plug my intake, then I put an air filter from a small ATV on the BOV just for peace of mind
