Hey all,

Was looking into tuning my GT3. I know there are a couple options out there now... Hydra, M-Engineering, Softronic, Pearson, Gintani, etc. But has anybody gone through with it, or know anybody who has? With 992 it seems fairly worth it, M Engineering claims +30whp and 25wtq with no exhaust mods, and a little more with some. Pretty sure it changes the powerband up a little as well, and the car should make a lot more torque down low. Looking for suggestions, options, and opinions!

Pretty sure you’ll be disappointed with just a tune and no hardware change.

If you want low-rpm torque, get a Turbo.

The M Engineering tune is a bench tune as well so ECU needs to come out and get shipped off to them. Without other mods involved a tune on a NA car will never be game changing or anything. Me personally, it’s not even a consideration on this car.

ipse dixit

Methinks you bought the wrong car.

Put ebay turbos on it

Is Hydra still in business?

I've tuned 90% of the cars I've owned, never a 911, but I've seen it is not well received by GT3 owners. So expect the snarky responses to continue in this thread. As a few stated, full exhaust needs to accompany the tune to get a real benefit. It would be surprising to consider a change in software without the supporting hardware as well. With full exhaust and software I've seen 40-50whp gains and that would certainly be felt

A tune netting only 30-40hp crank is not worth it. That's a negligible change that the butt dyno won't really notice. Tune and exhaust with better filters sure.

I know and actual dealer that just took in an AIM ES1100 build which runs 8s. To be just as PTS said, I've tuned everything I owned ever.... very big builds as matter of fact. The 911, I just don't see the point. As Ipse said, you bought the wrong car.

I doubt you will notice a 25HP increase. Not worth voiding the warranty and hurting resale. IMO if you are going to tune, might as well go all out and do the supporting hardware to make all that worthwhile.

Otherwise, I think headers are the way to go. I did Dundon headers an there was no tune required, no CEL, just bolt on. The sound is amazing.

There are other advantages to the tune besides the gains in power, which are material. Most tunes can delete the annoying start/stop functionality. More importantly, the exhaust valves can be programmed to be full time on or off as selected from the vehicle interface (I've programmed this to the diamond button). You can flash back to stock tune if you need to take it in for warranty work or for sale.

The exhaust functionality is superior to the common cargraphic solution as you don't need a remote control to operate it. And eliminating the start/stop is worth the price of admission in my book.

Whose software are you running?

M-engineering on my 992 TTS, and Softronic on my 992 GT3

What about softronic did you like for the GT3 that you didn't like from M-engineering?

f4bones

M-engineering currently doesn't offer the capability to reflash via ODB - if you need to flash back to stock tune, you need to send the ECU back to them. ME did an amazing job on my TTS, and would have preferred to stick with them, but we will see how the Softronic product does. So far Scott at Softronic has been great to deal with - I had to pull my ECU and send back to Scott for the initial unlock / flash, but he turned it around is a day and overnighted it back.
