2016 Ford Mustang GT - IMRC Rod Failure

[capt_sneaky]

Hey Guys I am looking for some advice. I found that the IMRC Rod has failed and now the flaps in the manifold are stuck halfway closed/open. I am looking to replace the manifold. The biggest thing i am trying to avoid is a tune which I've seen most replacements require one. I've been told that a 2015-23 GT350 manifold doesn't require a tune and just needs an adapter for the throttle body but on the website where i am looking to purchase the manifold it states a Tune is required could anyone give me some guidance on this? I've provided the link below

The GT350 manifold installed on the 2015-17 5.0 with 80mm throttle body and stock air box does not require a tune.
VMP is your best source for the TB adapter.
Taking this one step further the PMAS No Tune Cold Air kit can also be used without the need of an ECU Tune.

What about a roush CIA with the no Tune airkit?

Sure but Roush uses an insert to reduce the MAF diameter to match the OEM diameter.
PMAS No Tune is in a class of its own @ 120mm diameter MAF housing and their proprietary tricked out MAF sensor.

The GT350 intake will work without a tune and sets no codes. You will lose a little bottom end and it will run right into the rev limit. It wants a higher limit lol i swapped mine and had the PP2 tune on it at the time the IMRC failed . I drove it a week without any tuning change then had a dyno tune done. I would say getting a tune done will be well worth it but you can run the intake without issue. Good luck with whatever you decide
