Check Engine Light & the Blitz SBC-iD ii

I recently installed a SBC-iD ii boost controller in my WRX, and the check engine light illuminates periodically as a result. After speaking with the Blitz tech support hotline, they relayed the information that the boost controller should not be the cause.

I also have a AEM CAI and an Apex'i Auto Timer...

Help me out here; which one of these could be causing the problem, and what can I do about it?

The Boost gauge "T" connector was spiked at the manifold hose the hose right behind the alternator. I was thinking that it could be a problem with the newly created volume. I didn't cut the stock hose, and just connected the stock hose to the "T" and the other side is connected to the nipple with a 1 inch' long piece of tubing. The "T" connector is pretty big and I am using all the tubing supplied by the blitz kit. So I was wondering if the check light is due to boost or vaccum lag going to the valve or whatever that hose goes to.

So to fix this I would shortened the lenght of the vaccum line and connect the T connector to the stock hosing...
what do you guys think.

 

and the code you pulled was........

Really, it can be anything, especially the MAF sensor from running a CAI. Go to Autozone and get the code pulled for free. Then goto Oakos.com and look up the code that was pulled and you'll know where the problem is.
