[Official] "Do I need a tune with bolt-ons?" thread

Leroydsouza · 01-25-2015, 02:53 AM

Mods Currently On

Motordyne M370
Motordyne ART Pipes
Akrapovic Evolution CBE

My plan is to go FI but thats not happening anytime soon (7AT - rebuild transmission and all)
Should i get a tune ? Since i have the m370 manifold should i also get the stillen gen 3 just to compliment them ? What is this throttle bodies ? Do they provide NA gains ?
My AFR must be messed up i assume

(i should probably make a single thread for myself as i keep asking questions in every thread)

I am probably too late!!!! However, whenever you bought the M370 you should have had a tune lined up as well. I would not have bought that part without everything else due to the fact that it practically requires a tune. You also do not have cats due to the ART pipe. You, my friend, desperately need a tune

Hey guys am getting a NISMO CB for my z do I REALLY need a tune? Would a cat back make the car run rich or lean cus that's my only concern (very bad experience)

You won't lean out with a catback only. No tune needed.

Thanks RanRich

Hey guys, I am currently running STILLEN G3 Longtube intakes, ARK GRIP V2 CBE.

Every now and then i'll drive it hard and maybe get a p0300 code and just do a ecu reset and it'll go away. I figured it had something to do with having a more lean AFR while on the top end.

I just purchased a Tomei EXPREME Ti and going to mate it to a motordyne XYZ testpipe modular Y-PIPE and also got some BERK HFCs on the way as well...

My question here is will the ECU be able to adjust this time or will I definitely be running too lean and need a tune?

Thank you.

You would see a definite performance improvement, the general rule is 3 air mods for a tune and you have reached that level

Currently have Gen 3's along with a NISMO H pipe and mid pipe mated to a resonated axleback from Topspeed. Car feels way livelier and faster than stock, AFR on Torque Pro fluctuated from 11.8-13.3 on WOT. Not sure if that's accurate or good.

If you aren't getting any CEL's then you should be okay, but we always recommend a tune when removing cats.

What's the thoughts on stock intakes and a z1 modified intake manifold with z1 test pipes and random cbe? I know there would be power to be gained, not really worried about that but would it run dangerously lean if these few mods are installed?

Always a good idea to tune if you are removing the cats.

Currently Running AAM Short Tails, and looking at picking up the AAM midpipe and either the Z1 Intake or AAM Intake (leaning towards Z1 due to Price and not needing to cut for the install). Will I need a tune?

Anyone? Currently have Z1 Motorsports intake and AAM Shorttails.

jchammond · 02-23-2017, 06:58 PM

Z1 doesn't require a tune because maf's are in same location;just underneath pipe.
A tune would more than likely benefit anyone with a Z,mod's or no mod's.

jchammond · 02-23-2017, 07:02 PM

Started & was tuned with their base kit & exhaust...then upgraded the CAI

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