Great video, thanks for the heads up! Very impressive gains... Eager for them to crack the ECU on the 911.2 TTS.

Who did the tune?

GIAC. Most shops like Fabspeed offer their branded tune but they're also GIAC

9914s

This is only the beginning...

Wow. That is a huge difference for only $2000. GIAC is going to get some business I suspect. I was surprised that the tune also gives the car better MPG.

Just checked what GIAC can do for the 991.2 GTS...530hp/500tq. This is insane, cause that's really Turbo territory...

impressive numbers
I can't think of a reason not to do it

But muh Warranty!!!!!!!!!

Finally these tunes and videos are coming out. Takes me back to when the BMW E92 3.0TT first came out and people started tuning them and getting huge gains.

The fuel efficiency gain is mostly a theoretically one, only if you don’t use the extra power.

I'm curious what a GIAC tuned GTS would do... Would it crack 550hp?

Ive has two tuned cars and both I experienced overall MPG gains (small, around 2 overall, but there nonetheless) even with using the increased power. I track my mileage pretty carefully as I used to deduct it for business so I have solid data to back it up. It's definitely there, at least in my experience which coincides with the rest of what I read on the internet.

It's 530hp/500tq.
