DAMN! You guys write this sh!t fast! I just caught up to this post!!
Congrats on getting your JPP setup!
(so THAT'S what they look like new and off the car!!)
I was wondering if it was a matter of time before you started throwing CEL codes on that back sensor. That's where the Split Second box helped me out when they did the last tune. Their next option was to replace it with a more robust (higher temp/tolerance) sensor - but it's stayed in tune and no CELs fine for past several months now.
Note: CPe alone won't do it - even after re-mapping, because again, you will have issues with the sims and rear sensor.
I have no resonator and still no raspiness because
a) I have a TRD Muffler
b) I dont' have an Injen Intake!
Seriously - the Injen not only affects intake sound because of the restricted airflow, but also exhaust tone. It will also affect performance as you won't have nearly the gains that more airflow will provide you in the loop.
Anxious to see what kind of dyno numbers you end up with too. Helps to have a baseline though, so if you don't have numbers on the same car/same dyno before you installed, then it doesn't mean much I'm afraid. I ran out of funds to keep messing with mine and get actual dyno numbers before/after installs.
