    yup, and rich between shifts with the BOV, also extremely bad if you're running a catted uppipe. Leaving either on is probably the most irresponsible thing you can do regarding the life of your motor. But hey, its your car

    Well the BOV is making it run rich. I know that because it will pop occasionally inbetween shifts and BOV's are known to do that. My air/ratio meter is always green too especially at WOT even thogh I know those aren't that accurate. So, I really dout it's runnning lean. If anything it's making up for the BOV. Know what I mean

    I have a fully catless TBE, and running rich isn't going to hurt anything but my wallet. It's nothing compared to running lean

    the bov only creates rich conditions between shifts while the intake would cause you to run lean constantly. so it's not really going to balance out.
    you could always pick up an accessport and flash stg2. that will more than make up for the lost power from the stock box.

    um...no, it doesn't work that way.
    You really need to know what you're doing before you start plopping random parts on your car.

    We're trying to help you out and tell you that you're hurting your motor.

    If you want to make your car faster, a BOV and CAI are the WORST possible choices to make. Take 5 minutes and do a search for both on this site. Like I said, it's your motor man, we have nothing to loose, you do.

    We're trying to help you out and tell you that you're hurting your motor, but do what you will, we've got nothing vested in the car.

    You two are the only ones saying it's hurting the car. I bought the car with thses parts already on. Like I said my air/fuel is always in the green. Tell me how the BOV is hurting my car. The stock box makes the car lag. maybe my car is an exception. And I have also been told Accesports are garbage. they sell generic maps and no 2 cars run the same even with identical mods.I have read several posts of motors blowing. I am saving for an Ecutek and a tune at Ispeed. I not trying to say I know anything cause I am a nooby, I am just going by research.

    we're the only 2 people telling you not to do it because we're the only 2 people awake at this hour

    I would HIGHLY suggest that you read the stickies on this forum, especially the first good mods threads, as they ALL thoroughly discuss the negative affects of CAI's and BOV's to your engine. I would also suggest (again) that you do a search on this forum specifically for BOV's and CAI's, as you will quickly find out that you're not only NOT gaining any performance from your mods, but are actually hurting your car. Lastly, I don't know where you're getting your information from about any of this stuff, especially the AP, but sorry to say man, you're wrong.

    Take a few minutes, educate yourself, and then make your own decisions.

    Here's a few great threads to start your education with (took about 2 minutes of searching to find):
    Good first mods
    Engine Performance FAQ [[[READ ME]]]
    http://forums.nasioc.com/forums/showthread.php?t=533787

    Enjoy

    if your getting it tuned it doesn't matter what em you get and you can keep the cai. since you bought the car with those mods already on, then the previous owner has probably been running them since day one, so i'm sure damage has already been done

    you mind sharing these posts? I've never heard of a motor blowing from using an AP, assuming it was used properly. I'd be curious to get some more info on this.

    Do you agree that all rex's run the same with the same mods? I know a couple people that know someone with a blown motor after installing an AP. The maps are generic.

    I'd be interested to read the posts you're talking about.
    And the Cobb maps are programed within certain parameters. So yes, assuming they are used with the mods they are designed for, all rex's will run within the parameters that the map was designed for. A protune will gain even more power, but don't you think that if motors were blowing up from the Cobb maps they'd do something about it, or at least we'd see some posts about it? I'm not saying you're lying, but I'd be curious to know why these motors are blowing on conservative Cobb maps, it's not like they're pushing extraodinary amounts of power, they're only boosting at 16-17psi or so, with supporting fuel and timing maps, there's nothing particularly dangerous about that.
