Tune required for FMIC?

[Silverton]

I'm thinking of adding a cat-back, UICP and an FMIC. Is a tune required for a 2013 MR?

yes, your boost will most likely be to high.

I ran all 3 of those exact parts and those only for probably 7 mounts with no problems

Not required, but strongly suggested. You will not blow up your motor, but you will not be getting all you can out of the mods.

I did intake, UICP, LICP and an ETS 3.5" FMIC and CBE with no tune, never saw boost spikes.

In the research I did before doing that setup for awhile, I was seeing people with overboost problems also having a testpipe.

Is that because the wastegate flapper valve is too small & or the turbine housing wastegate hole needs to be inlarged?

I know on Syclones this is a problems also, mainly because the wastegate hole is too small.

Heres what i did to my car....

K&N drop in filter + AMS DP + T1R Res TP = 23psi
AMS DP + T1R Res TP + UICP + AMS CAI = 26psi
AMS DP + T1R Res TP + UICP + AMS CAI + ETS 4" IC + LICP + Tomei Catback = 30psi

All that parts and no tune. Once i had all those parts on, any time i went WOT, which was only once, the CEL would come on and the car would start bucking like a horse. I then installed my injectors, 3port and fp red and got a tune.

This. Don't mess around with the car because you want to try an save money. do it right and the car will be right by you. You wont notice much gains until you get a tune. With those parts + tune it will be a completely different car.

Do you monitor your car? Just because you haven't had a problem, yet, doesn't mean its okay for the rest of the world to do it. Again the tune is where the real power comes. Monitor your car and make sure things are good.

I was just saying, I ran all the bolt-ons in front of the turbo, and ran stock dp, stock cat, and with a CBE and didn't see any overboosting.

The day I installed my TP I got my tune.

When it comes to details about the wastegate on the turbo, I couldn't tell you. I for one am not going to actually swap my turbo and downpipe when I do next year. The job is a royal PITA on the X, and I know with my temper, I'll likely break one of the studs. So, I've never physically laid eyes on the OE turbo yet, other than pictures. I just paid attention to people complaining of overboosting without a tune. Most of them had test-pipes.

--> Snakes post is a good example, he was running a testpipe when he saw higher than factory boost.

I was using Torque on my phone connected to my ODB2 adapter, and would datalog my trips to work. I had it alarm anytime I hit higher than 23psi. The highest I hit was 23.1psi one time.



My general advice though, Do your bolt-ons, and then get tuned anyway. The car really makes a big difference in power above 5500rpms with a tune. It feels amazing

I swapped to a panel filter and saw boost spiking to 24ish on my completely stock 2010. When I put on my synapse piping/intake/DV kit I saw spikes to 27 sometimes.

No two cars are the same, quite a few people get away with more than I did without seeing spikes. You need to have some method of changing things in the tune (open source/Cobb AP) before changing hard parts if you want to be safe.

I had a tactrix cable before I bought a panel filter. I wouldn't recommend any other way...
