@MMM-im2ts normal for what? Anything with a Porsche emblem? I paid $750 for my 700whp ctsv to be dyno/street tuned. These are $1400 box tunes, not exactly tailored to each vehicle.
If you have any upgraded hardware, like 3rd party diverter valves, secondary cat delete, maybe high flow primary cats, you should always let a skilled tuner map you specific car. No generic tunes on modified cars. That will give suboptimal results.
@@eugeniodebenedittis2586 Yes, there is a pretty significant drivetrain loss on AWD vehicles. All dynos read a little different, the key is the change in power but those numbers aren't different from what we've seen from other Cayenne Turbos.
20% or greater drivetrain loss. The math is accurate. 500hp - 20% drivetrain loss = 400hp. 80 hp tune plus plenum 6hp = 486hp to the wheel. Give it 1hp for the air filters.
$1700 for a single, one time tune is an insane price though. I can only imagine tunes later on after adding even minor bolt ons.
That’s kind of normal tbh

12.31 @ 113.5 in my 958. 2000ft DA
Stock?
958 turbo should get 12.4 stock, without a tune or anything done.
This is great but what will it do for the 10 year extended warranty on the transfer case ???
Yes, interested in the answer to that. Can you flash back to stock w/o being busted by Porsche?
so what's better for the 958, something like this EVOMS ECU flash tune, or a piggyback JB4?
Sooo, why is there such a crazy range of ECU flash tunes from $1400 to $3200? jesus christ
Can you do a build for bigger turbos? Turbo v8 should be able to handle big numbers if the transmission can handle it
Hi, what are the 100-200 times on your stage? and what turbo pressure do you have in max and how it holds?
Any exhaust set recommendation before a $1,700 ECU flash ?
If you have any upgraded hardware, like 3rd party diverter valves, secondary cat delete, maybe high flow primary cats, you should always let a skilled tuner map you specific car. No generic tunes on modified cars. That will give suboptimal results.
any turbo upgrades available for the 958
Are upgraded diverter valves a must have with this tune or should the OEM ones be sufficient?
They aren't a must have but the OEM ones are prone to leaking over time.
@@Flat6Motorsports appreciate the insight!
Do you guys serve southern California
Yes, we ship all around the world!
Any update on the Exchaust video?
Installed, just need to capture video/audio. Probably will have it in the next couple of weeks.
standard coil pack?
Standard/OEM coil packs & spark plugs.
But those numbers? 487 hp after tuning? Something wrong...
Those are measured at the wheels not crankshaft.
@@Flat6Motorsports it lost more than 90 hp from the crank? It measured 500hp at it?

The dyno showed 487 HP at the wheel which is around 610 at the crank. The 584 TQ at the wheel is about 730 TQ at the crank....
How much $$$??
