you just need a new calibration for that CAI. MM's new calibration process is going to be a lot easier to get this. Plus you can datalog with the AP itself now, which is teh beer ****!!11!1

That tube with yellow strip on it that looks like it is going into the al. tube before the throttle body - if that is going to the air injectors then I think that is a problem - not sure it will fix your idle though .
You need to hook that line into the the vacuum side of the intake not the pressure side as you have done there . You also need to fit a one way check valve to it to prevent a pressure leak back into the intake under boost .

I got a check valve from a wrecker - lots or cars use the exact size you need on the vac line to the brake booster

actually after thinking this through some more - perhaps the way you have done it is fine .

Also : if you don't want to fill up your turbo with oil you need to fit a catch can on the line going to the oil fill vent ....

ill look into purchasing a catch can, can you point out where i would need a check valve? also i have a update so i got my adapter fitting to recirculate my bov and i ran into a snag the fitting that attaches to my bov is 1.25 and the tube that sticks out of the mazsport cai is 1" (after looking through the atp catalog i should have gotten the 1" adapter they had available now i have to order another) but my question is how did some of you guys recirculate the bov i cant find a hose that is flexible enough to bend at a aggressive angle...

another update, i was too anxious to see if recirculating my bov would fix my problem so i was able to get a ghetto plastic hose on and used duct tape to seal it...lol seems like i was able to drive the car and while coming to a stop the car stills stalls but i can prevent it from stalling by blipping the throttle as the rpm drops between 2-3k rpm it will struggle to stay on, during driving conditions the car feels really smooth and my afr's at wot are low 11's car feels really strong and put a smile on my face...after driving it a few times my long term fuel trim was at about 5-6. maybe i need a tune/adjustment by jeff now to get it perfect??

tried it, nothing there i could find that can bend at a agressive angle

it looks like the easiest way is to route a hose underneath the intake and still would need to be able to bend pretty agressively

Damn, that is aggresive, maybe flip the BOV around and run it around the top?

Hard to say man... that BOV inlet is in a real bad spot for your set-up.

do you think since my last update on how the car drives, an ap calibration can help the car come a idle smoother without me assisting the throttle?

I wanna say "yes" but without data from your logs when it cuts out - I can't really guess.

Rather than spending money on stuff like that, have you first just pulled the BOV vac signal and covered the discharge of the BOV with a rubber cap and see if that fixes you situation?

NP. I just don't like throwing parts at a problem - especially if the exact same setup was working correctly previously.
