I did open up the upper core a bit; so no pinching of the intake tubes.

Dyno results? Midpipe is next for me.

Mine right now.

Didn't like how tight the silicone in the rad supports but doesn't seem to negatively impact performance.

I'm thinking i used a 1/2" drill with a 3 5/8" hole saw.....carefully cut through the fiber's in the core.
Got a handle on the drill to hold tight-would suck to slip & nick a headlight or something.

BUMP!

Putting test pipes on with my full exhaust and JWT pop chargers + MAF tubes in a couple weeks. Am I okay to run (meaning spirited driving and WOT) for the time being without a tune? Or should I put the stock airboxes back on in the meantime to do this safely?

Getting a tune this summer, but not for a few weeks after install at the very least.

You'll be fine you just may run a little lean and possibly throw a code. As long as you know your getting the tune soon don't stress it too much

As in a code for running lean or for the test pipes? I'm trying to find time to head over to Dynosty for an EcuTek tune but don't want to grenade beforehand if I get a little playful with the car.

Would a tune be beneficial for K&N drop filters, stillen HFC, light weight crank pulley. still have OEM EXHAUST but looking for a better 1. I hate the delay throttle response. THANKS

I recently installed AAM Resonated Short Tails, Stillen Gen3 CAI, and ART Pipes. I was running with the Short Tails and CAI for a few months before I installed the ART Pipes and didn't have any issues throwing codes. Now that I've installed the ART Pipes I'm throwing codes for both 02 Sensors reading too lean. My car is still fairly new and only just passed the 8,000 miles mark. I won't be able to get the car tuned until the end of the year. Is it safe for me to drive the car with the mods installed or should I re-install some of the OEM parts to be safe? Reading through this forum I've seen mixed responses. Some people say that it should be safe and others say that the A/F ratio could be thrown off really bad. Is it possible that the ART Pipes are reading the A/F mixture incorrectly due to the 02 sensor placement? I'm just trying to be safe and ensure that I don't damage my vehicle. Any help is appreciated!

if there's a local dyno shop...throw it on there & ensure you're not running lean-as this will toast your engine.
we have a local in SC w/a Dyno-jet & he put's the A/F meter at the exhaust...it should be on the rich side @wot (12.0-13.0) unless you have a vacuum leak,etc...

I live in Tennessee and the closest UpRev tuner is Z1 Motorsports. It's a bit of a trip to get out there and as I said before, I really don't have the capacity to spend the money on a tune right now. In a few more months I will be able to. That's why I asked if it's safe for me to leave the parts on for a few months or if I should remove them and re-install them once I get my tune.

You can make dyno runs without tuning your car & see where your AFR is...unsure what a Dyno shop charges.
Our local shop use to be $50 for 2 pulls & he's gone up to 75...he also gives out printed sheets w/graphs,whp,wtq,and it shows AFR.
Custom tunes start around 600+ (this includes license).
I added FI TP's,exhaust & a CAI (didn't move the placement of my mafs) and it ran 12.20AFR before taking to get a tune...it never threw a cel & drove 5-600 miles before going to Z1 for a tune.

Also; what sensors are throwing the codes? And were any impact wrenches used on exhaust with O2's still in place?
