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

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)? |

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 |

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?

Maybe to get more out of it, the tune

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.

Is it possible to have the GTS startup roar but NOT the GTS throttle burble with a stage 2 flash?
