EVOMS in co-operative efforts with GIAC are proud to offer the safest, most powerful ECU tuning for the 996TT. The ECU program we offer will add 65-75 HP and 65-75 TQ.


VIVID
By reflashing your Porsche 996TT with the standard K16 turbos, you will expect to gain 80whp and 90ft/lbs of torque with corresponding modifications (diverter valves and K&N flat panel filter).

 

Sounds high and I would love to see a dyno of that.

Consensus is that a stage 1 (flash only) gives you 500 at crank.

And look at Evo's own dyno for stage 1. 38 at wheel.

 

I think the truth is you have to have a flash, free flow air filter, AND reasonably free flowing exhaust (100 cell cats with 2.5" tubing OR 200 cell cats with 3" tubing) to get an honest 500 hp at the crank.

Of course if you use a straight-through exhaust design like the old-school Fabspeed Supersport you can tack on another 10 hp.

If you get a better intake box (EVO, UMW, Vivid) I think you can up that figure again another 10 hp

The point is 45 hp for a flash is just wrong......even the FVD website claims 75 hp for flash only.....AWD dyno isn't making up for a 30 hp loss

 

Thanks for the info guys. I'll give FVD a call in the morning and see what they have to say about these numbers. All I have is TRUE before and after numbers for MY car.
No marketing numbers here, just the truth.
Now if I should have experienced higher gains than this, I want them.
Isn't that what I paid for?
I'll post their comments.

 

Any developments on this? I was going to go FVD, but maybe not now

 

I finally had a chance to call today, sorry for the delay.
I gave the guy my results and he said that they were right in line with what they normally expect. He wasn't surprised to hear people quoting "websites" and stating "my tuning is better than yours". He also mentioned that they tend to tune for drivability and reliability rather than trying to win the trophy for Largest HP Gains Quoted On A Website.
Their goal is to have happy customers who's cars behave just like they did from the factory, only with better performance. No intermittent check engine lights or "customer tweaking" necessary.
I for one am no expert on this subject but I can tell you one thing, I am VERY happy with FVD as a company so far. (No, I do not have any affiliation with them, I just believe they are good people) Being in the business for over 25 years, they must be doing something right.
On another note, and an awesome sounding one at that, I installed their exhaust this weekend and once again I am impressed.

Finally, for the record, my Tuning and Exhaust ARE better than yours

 

Since we are quoting manufactures numbers (cause they never "exaggerate")

Ya, maybe using manufacturers claims aren't quite as reliable as an acutal awd Mustang dyno.

msidrd; please post the dyno sheets.

 

After talking to the FVD folks I came away with the impression they are about good gains but not over stressing the engine or turbo. Those boost numbers are not what some tuners will use and hence don't generate the big numbers but they won't make your turbo run on the ragged edge. I am sure if you tell them you don't care about replacing the turbos they'll send you a high boost file. They also tend to run the fuel curve a little fat to ensure no fried valves. That can be leaned out to gain a few HP. I personally wouldn't go that route but I'm sure it's an option from FVD and many others. It's just a simple trade off of power for longevity.

 

OK Ace, here is the published data on the FVD website:

Genuine:
Engine - 6Cyl. Boxer Twin-Turbo
Capacity - 3600ccm
Compression ratio - 9,4:1
Max. Power - 309kW (415HP) @ 6000rpm
Max. Torque - 560Nm (413lbf ft) @ 3500-4500rpm
Max. Speed - 305km/h
Max. RPM - 6750rpm
Acceleration 0-100km/h - 4.2s

Tuning:
Max. Power - 360kW (490HP) @ 6000rpm
Max. Torque - 735Nm (542lbf ft) @ 4000rpm
Max. Speed - 318km/h
Max. RPM - 7000rpm
Acceleration 0-100km/h - 3.9s

So they claim 75 hp but deliver 45? Sorry, I'm calling the kettle black on this one. I was considering them as I wanted a laptop based tune with adjustability, but not any longer

 

Man, you really need to relax. Do you have any idea what those gains would equate to at the wheels? I am sure they are quoted at the flywheel just like everyone else does. All I am offering is truthful info on the gains that I experienced.
Can you post your before and after dyno results on the tuning you are currently using? Or are you one of those guys who has no personal experience but claims to be an authority on the subject with statements like "those numbers SUCK".
All I'm saying is I chose FVD and I'm happy.
Hopefully we can make this the last post in this thread because it really isn't helping anybody.

Question...if I'm Ace does that make you Gary?

 

You're right, if your happy thats what counts. Actually, I owe you a beer for exposing the truth so thanks

I am running stock and have committed to buying a flash this month so I have been overloaded with choices. Now there's one less choice.

I'm a Machinery Engineer by trade, working with 4000 hp turbocharged equipment every day so I'm very thorough with research before I buy performance upgrades......

Yep, move along.....nothing to see here

Gary

 

Hey, ya think we could fit one of those into our rides?

 

is it true that the tuning via OBD port is not safe ?

 

When I installed my FVD flash they made a big deal about making sure that the car battery was connected to a battery charger and that the computer had full battery while I did the flash.

I think that if the power went out there would be a possibility of corrupting the ECU.

 

wow thats 40% transmission loss!
