Hey guys,

I had recently purchased my 2015 Nissan GT-R last September (9/20). I love the car but would like to start on my first mod as most owners of this car do.

I had recently put a Tanabe exhaust/mid-pipe on the car last October.

I'd like to go into a stage 2 tune as I feel the car looses some of it's power on the top end/higher gears.

I was thinking about doing the AAM 3in intakes as installed on the Bros FOURR Speed YT channel.

AAM Competition R35 GT-R R-Line 3" Intake Kit: https://www.aamcompetition.com/shop/product/aam-competition-r35-gt-r-r-line-3-intake-kit-39625?category=27#attr=149

I was also thinking about ordering the COBB tuner from AAM.

I was wondering if any of you guys had any other recommendations for the ECU tuner or another company that may be better for the intakes. Any other feedback or good resources (websites, company info, contacts) you may have would also be greatly appreciated.

Thanks.

I have the same car and went with GotBoost Intakes, a used HKS mid-pipe, Cobb Accessport, and remote tune by Tim Bailey. This is about the perfect combination and relatively cheap for a nice bump in performance. If you want more (downpipes would be my next step), then you have to start doing fuel modifications (injectors, pump, E85 tune, etc).

Congrats on the car. My advice is to set a goal and only pay for mods and tuning once. For example if you are planning on going fbo e85 it would be cheaper to buy all parts and get tuned rather than buying intakes and getting tune then deciding you want more power. Then you would buy injectors/pumps/ flex fuel kit ect and pay for tuning again. It is a vicious cycle that we have all fallen into before.

I personally use the got boost intakes and ecutek tuning software to answer your question.

FBO = Full Bolt-ons (basically just "add-on" parts):

Midpipe

Tune (Ecutek or Cobb)

3" Intakes

Catless Downpipes

Inectors (at least 1050cc, 1300cc for more "headroom"/Flex Fuel or upgraded turbos)

* Catback exhaust and Intercooler upgrade optional

If running E85 is in your plans:

Flex Fuel Kit

Upgraded Fuel Pumps

Plan on 600 WHP/600WTQ at this point, depending on your location and aggressiveness of your tuner.

Intakes are probably all the same these days. Dave @ Gotboost are the OGs. Can get different materials, ie. carbon, titanium, etc. from other mfgs.

The fall off is the stock turbo, runs out of steam at higher rpm.

You can go with Cobb or Ecutek for a car. Go with the latter if you plan on building the car at some point or non-sniffing emissions/inspections are/will be an issue.

So is Tim the main tuner at Cobb? Sorry I'm not that familiar with him. It looks like the 3in intakes would cost around $600, while the Cobb access port would be around $400. Although would you recommend remote tuning with any company I decided to go with?

Not sure why the AAM Cobb is so much more than Cobb access port on the Cobb website ($795 vs $400)

AAM website (Cobb access port -- no remote tuning): https://www.aamcompetition.com/shop/product/nissan-gt-r-cobb-accessport-44122?category=91#attr=59,69,67

Would you guys also recommend this upper I/C pipe kit in addition to the intakes or is it not really worth it? https://www.aamcompetition.com/shop/product/aam-competition-r35-gt-r-upper-i-c-pipe-kit-twin-tial-bov-s-39686?category=27#attr=35,48

If I decided to do catless downpipes are you then pretty much forced to do the injectors/pump?

Thanks to you all for feedback/comments.

You're probably looking at the TCM upgrade for the COBB on their website. TCM is a transmission tune.

This is the product you need:

https://www.cobbtuning.com/products/accessport/nissan-gt-r-accessport-v3-ap3-nis-007

I have one for sale if you want. Used it for 2 years and then swapped over to an EcuTek. Comes with everything besides the sticky mount which I go against since it has peeled off some of my clear on the carbon AC panel that it was stuck to.

https://www.cobbtuning.com/products/accessport/accessport-v3-sticky-mount-1

I would go Downpipes, Midpipes, Injectors and Pumps. Since you're doing that you can throw in an E85 sensor too. You are forced to do Injectors and Pumps if you're going to do Downpipes. Something about maxing out stock injectors with Downpipes? You can very with a tuner or a vendor here for an accurate explanation.

https://www.gtrlife.com/forums/topic/286682-do-you-need-upgraded-injectors-to-run-downpipes/

You can do without the Full Exhaust, Upper Intercooler Pipes, BOV, Speed Density and Intercooler Upgrade for FBO goals.

Thanks WholeGrainHomie, I don't know if the version on the Cobb website and AAM website going for $950 is the overall accessport (V3/version 3) and the $400 option is maybe just an upgrade to TCM flashing?

$950 V3 Cobb Access port: https://www.cobbtuning.com/products/accessport/nissan-gt-r-accessport-v3-ap3-nis-007

$400 Cobb Access port (TCM upgrade): https://www.cobbtuning.com/products/accessport/2015-2018-nissan-gt-r-accessport-v3-upgrade-to-tcm-flashing

How much are you selling yours for?

The one AAM is selling for $950 is the Version 3 Accessport that you need for tuning. Just ensure its a -007 version, this is for 2015-2018 GTRs.

Mine doesnt have a TCM flash so you would have to pick that up if you want a TCM tune. You can always pick it up in the future. I drove my FBO for 2 years without the need for a TCM tune.

Ill sell mine (AP3-NIS-007) for $450 shipped

Tim Bailey used to work for Cobb. I believe he has since moved on but still offers remote tunes. He is extremely knowledgeable, a nice guy and a helped hundreds if not thousands of people over the years. He offers a fairly conservative tune and offers a TCM (transmission) tune as well.

If you are just going to start with a midpipe, can use an OTS (off the shelf map) from Cobb. You’ll be leaving some hp on the table, but not much.

Can pick up a used Cobb like @wholegrain’s above. If down the road you want a TCM tune to stop the car from upshifting at part throttle, can sell the AP pretty easy. I went 4-5 years before having a TCM tune and if you drive mostly in manual won’t e much of a difference.

Forgot to clarify there are two Cobb Access Ports (AP) for the R35

NISSAN GT-R ACCESSPORT V3 (AP3-NIS-005)
$795

NISSAN GT-R ACCESSPORT V3 (UPGRADE TO TCM FLASHING)
$400

NISSAN GT-R ACCESSPORT V3 (AP3-NIS-006) W/TCM FLASHING
$1,195

They work out to be the same if you upgrade to TCM down the road.

Don’t go with a V2 they are buggy, are not supported and most likely will have issues down the road.

All depends on what fuel you plan on using.

I'd be down to buy the AP3-NIS-007 off of you, if it's still available. If I were to just do air intakes initially could I just use a stage 2 map that's available, or would a remote/e-tune be the best way to go? Wondering how much Tim Bailey would charge if he's still reachable. Looks like AAM does remote tuning for $695 w/stock injectors when you buy the Cobb access port from them.

PM'd you regarding my COBB Accessport. I would just do the OTS (Off the Shelf) map if you're going to do just the basics for now. It's free and you can get them off COBB's website if they not already preloaded into the COBB. Doesn't make sense going bonkers with the tune if you're not going Full Bolt on. $625 to just tune for Air intakes is way excessive.

I would look into vendor reviews about AAM here on this site before deciding. Personally I would avoid them.
