[sudden urge]

Okay just completed installing my JBA cat forward headers with factory cats and cat back Magnaflow exhaust. i also have an AEM Brute Force intake.

My question is I have my Superchip Cortex currently running the 87 octane tune should i be re-tuning it and does the Cortex have the ability to read A/F i cannot find it in any of the parameters thank you in advance!

You can monitor the AFR with Superchips if your Titan is a 2007-2010 model. At their website, they have a free download for this application in case your Cortex doesn't have it installed. I forgot where in the menu the sensor monitoring is, but it's there somewhere...lol.
