EVOMS Tune for the 958 Cayenne Turbo (Build EP 7) tested on the dyno!

[@miraclebvlk]

Hi, what are the 100-200 times on your stage? and what turbo pressure do you have in max and how it holds?

[@elcolin_]

so what's better for the 958, something like this EVOMS ECU flash tune, or a piggyback JB4?

[@elcolin_]

$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.

[@MMM-im2ts]

That’s kind of normal tbh

[@DizzKidz]

​@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.

[@gtrguyinaz]

This is great but what will it do for the 10 year extended warranty on the transfer case ???

[@bhaure]

Yes, interested in the answer to that. Can you flash back to stock w/o being busted by Porsche?

[@bhaure]

Any exhaust set recommendation before a $1,700 ECU flash ?

[@fm8453]

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.

[@Khalidsvt101]

any turbo upgrades available for the 958

[@lifehackertips]

Can you do a build for bigger turbos? Turbo v8 should be able to handle big numbers if the transmission can handle it

[@elcolin_]

Sooo, why is there such a crazy range of ECU flash tunes from $1400 to $3200? jesus christ

[@totoole6262]

Are upgraded diverter valves a must have with this tune or should the OEM ones be sufficient?

[@Flat6Motorsports]

They aren't a must have but the OEM ones are prone to leaking over time.

12.31 @ 113.5 in my 958. 2000ft DA

[@lifehackertips]

Stock?

[@lifehackertips]

958 turbo should get 12.4 stock, without a tune or anything done.

[@GODWITHUS0712]

Do you guys serve southern California

[@Flat6Motorsports]

Yes, we ship all around the world!

Any update on the Exchaust video?

[@Flat6Motorsports]

Installed, just need to capture video/audio. Probably will have it in the next couple of weeks.

[@aahzap2804]

standard coil pack?

[@Flat6Motorsports]

Standard/OEM coil packs & spark plugs.

[@eugeniodebenedittis2586]

But those numbers? 487 hp after tuning? Something wrong...

[@Flat6Motorsports]

Those are measured at the wheels not crankshaft.

[@eugeniodebenedittis2586]

@@Flat6Motorsports it lost more than 90 hp from the crank? It measured 500hp at it?

[@Flat6Motorsports]

@@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.

[@drayday3794]

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.

[@bigdogstreetperformance6761]

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....
