GT350 Manifold without a tune: Is it safe?

[Ange1c0w]

Hello friends! This is in fact my first post to this forum so let me give you a small run down.

I have a fully stock 2015 GT Premium other than a Borla catback exhaust. Naturally, I am looking to upgrade my stuff and have found a killer deal on a GT350 manifold and an airaid CAI. Well the deal is great other than that I have to trade the seller my stock manifold and intake on the spot of purchase. I don’t mind giving up my stock stuff, but the setting in which we are trading our parts to each other does not permit for tuning obviously. This is where my question is presented. Is it safe to drive my car from the shop location to my home without a tune to compensate for the new intake parts? Obviously, I would take it easy and would not beat on the car (despite my deepest urges) during the drive, but even then the thought of me messing something up from a small drive frightens me.

Please let me know if I am an idiot or if I can get away with leaving my car parked for a few days until I can get a tune.

No.

Your best bet is to purchase a tuner/tune in advanced, specific to your modifications. You can get a pretty decent tune from a reputable tuner and have revisions made later should that be desired.

Driving untuned on a tune-required CAI alone can create issues. The car may not even run, or hardly run swapping the IM on the stock tune.

I'm not sure that's accurate. With active IMRCs, which have the same actuation parameters/wiring as the stock manifold, and the associated vacuum lines that connect to both solenoids, it should run fine. The biggest potential issue is if your throttle body or injectors are not stock. If both are stock, it will be fine. The tune is not optimized for the runner lengths and volume of the GT350 manifold (Rev limit, VCT tuning), but it will drive and run fine. The airaid CAI is a no-tune CAI unless he cut out the "insert".

You can get away with the intake manifold and CAI (if it's a "no tune required" style). It won't be optimal, but it will drive fine.

What you can't get away with is the injectors and if the CAI is of the "tune required" style meaning larger MAF diameter. The engine will barely run if at all, and forget about actually driving it. It's best to get it towed at that point, or have the guy come to your house to swap the parts and wait to drive the car until it's tuned.

Leave it in garage until you get your tuning devic . My 18 manifold sat in my garage for three months lol.

you can get a cheap 2015-2017 intake manifold for $50 if you look. If you aren't changing injectors then it will be fine to drive home with long as you don't flog it.

It depends on the CAI. Like said earlier if it is tune required the car probably won't run.

If it is a no tune required CAI you would be ok driving it home.

Ask the person you are swapping with if it is tune required. If so get a e mail tune in advance.

you know, has anyone tried driving a car with the MAF unplugged? There's gotta be a failsafe the ECU resorts to on no-signal. It's the garbage signals from one of those large diameter intakes that gives ECU fits.

My old LT1 F-body you could run without the MAF sensor connected. It wouldn't run well, but it could use TPS and the map sensor to get you home.

You will need a tune in order to drive the car with the Gt350 set up if it is a tune required intake.
