Before I got the X-Charger, I had Flowmaster and BBK Cai on my 2005 V6. Never had a problem and it was a nice improvement on my HP.

Don't badmouth the BBK CAI, it's actually pretty good, at least it was for me.

 

Maverickaf17 Im glad your bbk worked for you. When I spoke with bbk they offered to send me a new intake tube under warranty but they were out of stock and had to make more. It was going to be a 2 to4 week wait. Thats why I gave up on bbk. They were very friendly to deal with and I give them a +1 for trying but I tend to get impatient so I returned the BBK intake and exchanged it for my louvers.

 

You said 0174

p0174 System too Lean (Bank 2)

Go back to stock and if it doesn't trigger then its probably the tunewhichmeans call Doug.
Ifit still trips stock then its something wrong with the car and you'll have to get it fixed the hard way. Could be any number of things.

 

I was the first one to say with having problems with BBK's intake. The best thing to do is clear the codes again.On your tuner set it for 87 pre loaded tune. I also would see about getting it dyno tuned. If you have the money buy the TI intake from Moonstang. On your tuner choose intake and it will come up then you should not have a problem. He's selling it for 100. Good deal and luck.
