There is still more work that needs to be done on this particular car. And for the first several months, I don't anticipate doing ANY mailorder work. There will be only in-house custom tuning we get a good assortment of baseline maps. But what fun that will be! I don't think Porsche owners have ever been presented with such a service until now. It's really interesting to see that the simple act of a baseline dyno run involves them dismantling the driveshaft and converting the car to RWD. This is because AWD dynojets have been known to eat viscous coupling center diffs for lunch since there is no fore-aft wheelspeed control between the two rollers.
As for EVOs, we do intend to apply this technology on that front as well. But more work needs to be done. There are very interesting things around the corner-- for reflashes as well as XEDEs

Right now, only Porsche. But notice the italic on "right now"

Shiv you are a jack of all trades when it comes to tuning. It's very impressive! Tell us a little about the boost on the 996 twin turbo. How much are you increasing boost beyond the stock settings?

Shiv how large are the stock turbos on the 996tt and what would be the jdm equivalent?
(keep the 996tt thread updated because it looks like an older sibling might be getting one soon due to evo envy )
I also can't think of any vw/audi/porsche tuning solution that does custom dyno tuning, they just load maps onto your ecu.

1 bar is pretty tame compared to what I've seen and tested from off-the-shelf reflashes for the 996tt. But ours is making considerably more torque across the board. Mainly because it runs rich as possible without killing power and doesn't pull back timing everywhere (just at 4800rpm for now.) Interestingly enough, this iisolated knock retard event is only showing up 20% of the time when doing pulls on the highway. That's mostly attributable to the fact that our dyno facilities aren't set up as well as they could be when it come to cooling side fender mounted intercoolers and rear-mounted air filters. There is a 50 deg F difference between air filter temps between dyno and road... something we NEVER see with EVOs and other front engined cars. Fixing this cooling issue is tomorrow's task Need to get it done by 3pm because we have an Elise coming in for XEDE tuning in 3.30pm

We can't possibly be the only one doing it right, can we?
Besides RUF.
Friend of mine got his work done at Evolution Motorsports (http://www.evoms.com). Although I don't know if his flash is custom or some baseline map. The gains are similiar to yours though. 100 wtq on an otherwise stock vehicle.
EDIT: while I'm thinking about it -- yeah, the 996 turbos are pretty small (relatively speaking). Combined with vanos lag is minimal, even at high altitude. I think I have a compressor chart in an email archive somewhere. I'll see if i can find it.

996 market is going to be tought to crack, they will NOT deal with "It will be done in a week" crap because they can go anywhere to get work done. Also if you blow one up it's not 3-4k to fix like a evo. It is the same type of work like my NSX, I spend money on Comptech because they are good and proven and backed by acura. Is Vishnu going to be sold like this or just a tuner in cali and no local support?

Insurance? What do you think a premium for an errors and ommisions policy would go for on a risk like this? Although the Dyno would make for some nice collateral
