IX BOV is great but leaks at 26PSI or so. Get a Synchronic BOV. I have one, better then stock, no ****. I topens under the most miniscule amount of boost and offers better then stock drivability.

 

When i get one im going tial qr so that i can just convert it to tial q bov when i go sd.

 

Why spend twice? Get your tuner to tune the car for the non recirc and be done with it.

 

Wont i need to go sd to run a normal tial bov

 

I didn't I ran it with the stock maft for the first few months then my maf took a **** so went sd.

 

Id say cams, a ported exhaust mani, licp ic and a boost controller personally. Whats your budget you have to spend??

 

i will be spending a few Grand. over the next six months i have a mbc at home

 

Bad advice here. The tuner can't "TUNE" missing air from your system. The car will just dump the gas it thinks it needs and the air is spent. The more boost you run the worse the prblem is. I run a BB RED and it is recirqued. Get a proper BOV setup or your drivability can be compromised.

Like I said I run the Synchronic Unit, the older one at that and it opens under ANY posative boost, the stock won't do that until it sees 5PSI or so. The drivability is so amazing I can't believe it. Dumping air into the atmosphere with a OEM maf is a dumb move.

 

Really? Go tell my tuner he don't know how to tune because I ran like that for months with no issues. Just make sure you have the right spring in it when you put it in.

All your tuner at the time did was change part of the flash to try to "band aid" the fact that the car was on MAF with a non re-circ valve. It was very popular in the early days of flashing (2005-2007...just like the hacky ways folks worked around making aftermarket intakes work then) but it doesn't mean its a smart thing to do nor should it ever be recommended. Heck, once the car is back in a good setup then you paid to fix part of the maps that didn't need to be changed in the first place.

Personally if there was a tuner recommending this approach instead of the correct one (either stay with re-circ or go SD) anytime in the last 3 years I'd switch to a new tuner.

 

What;s hsi name and phone number I'll call him now. Band-Aid and not good for the car. The more boost the more of an issue, especially with a bigger turbo. The MAF has no idea you spent that air. Just recirculate it. Your tuner is not smarter then a Mitsu Engineer.

 

Dumb question, but how does running speed density over maf help with a vent to air setup?

 

it's not a dumb question to me.

 

speed density instead of measuring the volume of air coming in the intake and converting it to a voltage the car reads through the mass air flow sensor. A pressure sensor is placed instead at a different point, most of the time on the intake manifold. The cars ecu will read that pressure sensor like an airflow sensor, in a sense that the voltage it gives to the stock ecu to help determine proper air fuel mixture. However its measuring psi rather then load for the ecu.
Pros: better driveability, smoother start up, better hp (no honeycomb to restrict)
Cons: If you go to places with different elevations, then the car might run differently, due to atmospheric pressure being at a different level at different elevations. If you live in the midwest or some place where elevation stays about the same your good, but if your almost 2000 ft elevation, with changes from 500 ft to 4000 ft, in a 1 hour given direction like where I live, not really worth the extra hassle. Good, but not good for my situation.
Hope that explain it

 

good to know. not for me, i like hooning in the mountains.
