Stage TWO firmly requires aftermarket downpipes, which means the
MPE exhaust (with factory DP's) will only qualify you for Stage ONE.

The Stage TWO calibrations take advantage of the reduced back pressure
and subsequent lower EGT's in order to make more power in a safe and
reliable manner. Running a Stage TWO file without the proper hardware
setup can result in poor drivability and potential engine damage.

The benefit of OBDII Port Flashing / MAP Switching is that it's very easy
to upgrade when the time comes. It's a convenience feature that allows
for future upgrades without having to revisit a dealer.

On the comfort is like stock but when you use Sport+more throttle more response more faster. Not sure about sport I always skip to Sport Plus...Lol

Is this true? Once tuned, does comfort, sport and sport+ do anything anymore?

Any insight would be greatly appreciated.

Also, asked if I got stage 1 done now, how much would be it to go up to a stage 2 after I got me dp and FMIC. They said full pop on price again for stage 2.

So the Stage 1 & Stage 2 maps are standard OTS maps? I was told that the dealer does a custom tune. Is that not the case?
If I buy a Stage 1 map locally, can I then purchase Stage 2 from you guys direct (for $100)?

Yes, they can be described as "Off The Shelf" by the fact that the software
is pre-engineered, tested, and validated for distribution through any of our
Certified HEX Tuning Installers.

That being said, all of our current Stage Level software options see
significant in-house dyno and on-road testing and validation before
release; which comes with far more expertise and experience than
one could argue you'd get from a single custom tuning session.

That is correct as well. Once the ECU has been "unlocked" all flashing
or MAP switching functions are a process you can execute yourself.
When it's time to upgrade form Stage ONE to Stage TWO you can
purchase the file which will then be e-mailed to you.

I can't decide on an exhaust and was thinking of just doing a catless downpipe with the stock exhaust. Would I still be able to do the stage two tune?

No. You just need an aftermarket downpipe whether it be catless or high flow catted (200 cell), stock exhaust is completely fine.

I've specifically asked this question to vf engineering before and their response was always that I needed an aftermarket exhaust.

Would like secondary clarification though

I had the stock exhaust with the VF Stage 2 tune...

I'm sure VF can confirm too.

When most people hear exhaust, they usually think of a cat-back, but a downpipe is part of the exhaust "stage." Aftermarket exhausts are really no less restrictive in terms of back pressure / exhaust flow than stock. But trading the stock downpipe for one with a high-flow cat, or no cat at all, allows for decreased back pressure / increased flow. Tuners can take advantage of this by having boost levels taper less quickly at higher RPMs since there's less load on the turbo and motor. If you ran VF's Stage 2 map with the stock downpipe, you likely wouldn't cause any immediate damage, but the increased heat levels and stress on the turbo itself would definitely shorten its lifespan. Bottom line, you only need to upgrade your downpipe for VF's Stage 2 tune. This is supported by the very first post in this thread and the fact that the Stage 2 dyno plot was done with the stock cat-back and an ER downpipe.

I was told by VF that a high flow cat like Fabspeed won’t do for stage 2 and it needs to be a catless downpipe. Anybody running stage 2 with high flow cats?

I'd bet because they did the tune with a catless downpipe and don't want to be on the hook for anyone who has issues running a catted one. Easy out for them. Honestly can't imagine it'd be an issue for a daily driver. For a tracked car, though...maybe not ideal.

Just keep in mind that if you want to add it back later, it's a separate performance
file which will cost $100.
Is it possible to have the GTS startup roar but NOT the GTS throttle burble with a stage 2 flash?

Yes, that is possible.

You'll just make that request at the time of purchase
and the tuned file will be created with no "burble".

Yes there is, by selecting the different drive modes, the "burble"
duration and aggression will change.

Efficient = No burble. Sport = Mild burble. Sport + = High-burble.


There are quite a few factors that influence the "burble" sound
quality, both from the calibration strategy we use, as well as the
physical arrangement of the exhaust system itself.

Cars with aftermarket down-pipes and resonator delete will be much
more aggressive sounding with sharper "pops" and "bangs". Cars
with factory downpipes will be more mild and controlled sounding.


Example: Stock Exhaust - Stage ONE Software

Example: Stock Exhaust - Stage TWO Software

Both of those vehicles have identical calibration strategies for the
throttle overrun (aka: burble). The only difference is the exhaust
configuration.
