the tunes will get about the same power because they are all subject to the same engine. You can get more power if you have free flow filters like bmc and a open exhaust like cats and mufflers and xpipes, the evomsit is learning software so it will adapt to mods if you have them. Main advantage of the tune is to make it more responsive and open up all the hp available in the engine that is detuned by the factory

I'm not trying to bash on people who have parted with their money based on no real data of performance improvement but at the very least try and do some research on any independently verified gains you may be seeing from these tunes. If you happen to come up empty.... well thats data.

The root meaning of a tune/calibration is that you program the ECU to do things that match the physical behaviors and capabilities of the engine. Just like you tune a piano to play on key with a certain note, you tune the ECU to play on key with an engine. Sometimes on a stock engine, the tune will get you an improvement due to something Porsche did for emissions, marketing, driveability, or extreme condition endurance reasons. Older cars like 996s and 997.1s see some decent gains from just a tune with no other mods, around 10-12hp depending on fuel. Newer stuff comes very well optimized from the factory unless you're running really good fuel. However, once you start changing hardware on the car (especially changing out stock components for ones that perform far differently, and hopefully better than stock), the stock ECU programming no longer matches the physical behaviors/capabilities of the engine, and there is room for improvement. Sometimes those changes are pretty minor, and the ECU's adaptions (there to ensure the car runs clean and consistent throughout its life as components wear) can adjust to them pretty well. Other times, the behavior of the engine will change in a way that the ECU's adaptions/corrections can't keep up. This costs power and makes the car drive with stumbles and hesitations as the car either wants to ping, or goes from correcting for a too-rich condition to a too-lean condition. An ECU tune purpose made for the different hardware upgrades will fix all that and the car will simply drive much better (smoother, more responsive, wider powerband) in addition to making more power.
With the nature of the tune, it is entirely possible to have multiple companies arrive at essentially the same place and make the same power with the same powerband on a given set of upgrades. In fact they should if they're doing their jobs right. Often the differences between tunes come in extra features and character. For example, we do a lot of work with the pedal mapping in most of our tunes. Especially on older cars, this makes an ENORMOUS difference in how the car responds to the driver in any condition, not just wide open throttle acceleration, and makes cars running our tuning feel different from other companies who just add power with fuel/spark/general map adjustments. You'll also find differences in extreme conditions. We're used to tuning cars on crappy fuel in super AZ summer temps at varying elevations due to our location and local environment. Because of these extremes, we are conservative about keeping component protection/safety maps intact, so in extreme conditions the car will have the ability to revert back to stock or near stock and protect itself just as the factory intended and slapped a warranty on. Some tuners do not do that, and disable or modify these protection/safety maps which can have reliability consequences.

Haven't done anything on my current GTS, but put an FVD tune on my ex-6GT3. Because I was taking it to a street- only car, i wanted to beef up low-end and mid-range. Spoke with Rhonda on what I wanted. They developed a tune for me considering my Cargraphics mufflers. She told me to expect to see about a 15-20 RWHP increase with the tune in addition to the moving of the power curve per my request.
I had previously dyno'd the car at 325 RWHP. Dyno after the tune was at 340. Right on the money. But, more importantly to me, the car was more streetable.
BTW, I bought the tune when they were having a special, $800, I seem to recall. Don't think I'd have done it at the regular $1200 price.

Thank you to everyone that provided me great info. This gives me lots to work with. I realize any tune will not give me huge gains, but smoother throttle and a little bit more power would be great. I will also order some BMC filters.

Feel free to give me a shout if you ever need anything,.
I didn't find much searching the threads I'm sure this topic has been beaten to death. Would love to know anyone who has done a ECU Tune. Just installed the sharkweks/ gundo and would lastly like to add a tune for a little extra power and smoother delivery. Any help would be great.
Our 997 ECU Tune is a fantastic way to pick up more power/tq (in-house dyno below) along with overall driveability improvements - better throttle response, smoother/more linear powerband etc.
Install is by way of a MyGenius handheld device which stores both your OEM & optimized files and plugs in via your OBDII port.
Tune files are custom tailored to your application - what upgrades you have, what fuel octane you run, street and/or track application etc.
Please feel free to give me a shout for more info or for forum pricing

I will say that there are relatively few customers who do their own validation to make sure their mod adds power or performance, and there are even some places selling tuning that do minimal validation of their own product as well.

I have the FabSpeed dual intake and full exhaust (cats, headers, mufflers, center muffler delete) with an ECU tune. The shop that did it said it was about 20 hp, by interpreting reading they were getting on a laptop. From what I could tell, they ran the car, captured a bunch of data, sent it somewhere and got a tune back in about 15 minutes via email that they load into my tuner, repeat until they were happy. I don't drag race it, but I did exercise it enough to know there was a difference. So did my son-in-law who builds and tunes imports and a driver from the speed shop that did the tune. It did not change the throttle sensitivity at all. The most noticeable difference is the way it winds in first and second gear in manual mode; incredibly quick. The only down side is now I want more!

It didn't instantly give me turbo power but torque moved lower in the rev range a bit and there was a significant boost in top end HP. I don't think they're lying with saying close to 10% which in this car is near 30 whp. Again top end. it's less noticeable around the lower/mid range.
I planned to do a same day stock vs flash dyno run last year but didn't get the chance. Easy to do since this can be flashed on the spot and I'll do it this year.
I'd say it was worth it when I picked it up on sale for about $600. Over $800? Tougher call. Though this is easy 'bolt on' hp. No installation cost.

My 997.1 C2 has a Vivid Racing tune. I have headers/200cells/straight pipes/GT3 throttle body with matching IPD plenum and a custom 82mm air intake with no bottlenecks. My particular tune is a "race only" tune, so I need to revert the car back to stock tune for state inspection/emissions, but that way I get to feel the difference between tunes at least once a year, and the change is noticeable. The top end acceleration from 5k-redline with the tune screams in comparison and the overall drivability is more fun and sharp. I can't speak for how the tune influences without the other parts in collaboration because I installed everything directly after purchase and asked Dan at Vivid to tune accordingly.
