I'm sure he will bash me from the posts I've seen him reply in! No problem I can take opinions positive or negative. I'm just wondering if the upgrades from Gemballa and Techart are realistic in power gains.
Thanks
Bashing sounds so negative...I'm just trying to help you guys since I'm living in a radius of around 200 km of four major Porsche Tuners.
You can imagine how many people I know who bought their products and who were able to provide their experience.
A lot of Porsches drive around here in Bavaria...
Gaining up to REAL 70 HP through a motronic update only is possible. BUT: I've seen with my own eyes two broken Cayenne Turbo engines and, surprise, surprise, both were tuned.
This may be related to a general "problem" with Cayenne tuning: no Tuner has actually experience with the new Cayenne Turbo engine and a lot of software mods were done by Audi Tuners who just didn't have much experience with Porsche engines. And these base software kits made it to most Porsche tuners who maybe tweaked a few parameters but the base programming was there.
Since Porsche offers the powerkit, some Tuners apparently got more clever and started to use the Porsche software as a basis for their software mods. Unfortunately this software also includes new parameters for the suspension black box for example. So I wouldn't be surprised to see problems with that too.
And finally: in my opinion, the standard brake system of the Cayenne Turbo can hardly "take" the power of the 450 HP. I highly recommend the powerkit because of the improved brake system. And you also get a sportier ride and a more direct steering feel too due to the modified suspension (not only software!!!).
And last but not least: the Cayenne Turbo engine is very new. Nobody has really a clue how good or bad and how reliable it is. So it might be a good idea to have a warranty for the engine...just in case.
People should have their dealers look up the price tag of a new engine in their parts computers, just a friendly hint.
And if Porsche finds out about the tuned engine software, you're busted. There is NO WAY how to hide the tuning from Porsche, if they want to find out (and they surely want to if they have to pay for a new engine), they can find out. The claims of some Tuners that their engine software mods are undetectable and can be totally reversed are a LIE.
Even if the old software is used again to hide a software mod, the maximum boost pressure for example of the tuned software is SAVED without the possibility to erase it.
Just one example. So if Porsche checks all black boxes and finds out that you had a max. boost pressure of 0.8 instead of 0.65, you're BUSTED. Not only the warranty for the engine is gone but the warranty for the drivetrain, gearbox, etc. as well.
The best example is the case of a fellow 996 Turbo owner who asked me if he should tune his car a few years ago. His tuner claimed that the tuning (software only) is undetectable, it was some sort of piggy box.
I advised against it but he did it anyway. Result: his engine broke down after half a year or so and Porsche sent an engineer or technician to his dealer to check out what happened. Result: around 50000 US Dollars engine repair/replacement cost for our fellow forum member. Ouch.
So please don't look upon my posts as bashing, I'm just trying to help and to show you a broader view of the whole situation. You can do what you want, it is your money.
Just don't say I didn't warn you. Of course you can be lucky and NOTHING happens and you'll drive around happy.
BTW: avoid tuners who promise everything, honesty is very seldom in that business. We visited Sportec in Switzerland (a report will follow as soon as we have some time for it) and we were impressed with their skills. And the best part: they didn't try to tell us BS, they told us exactly what we already knew...and expected from an honest business man.
So if your tuner tells you that his tuning is completely undetectable, bust him. If your tuner tells you that he got his software directly from Porsche and this is some sort of prototype software, bust him. If the tuner tells you that the software has been developped by Porsche but they don't want to make it public or he got it from a Porsche employee, bust him. If a tuner tells you how good his relationship to Porsche and the employees is, bust him.
I think you get my point...
And also avoid "mail software", meaning: they send you an engine black box and you send in yours in return.
The ONLY way is to have YOUR engine black box modified.
Much better: to leave the car at the Tuner and the Tuner modified the engine software INDIVIDUALLY on the dyno and based on your car. Only VERY few tuners actually do that.
Have a nice day...
That's what I love about this forum!
:D thank God my best friend works in the dealership LOL
