Just dyno my o2 tt got 368 awhp and 385 tq with a just a flash is this
sound about right?

 

I thought factory numbers were 360-380 awhp? I didn't have mine on the dyno, but this is what they had told me. What did it dyno before the tune? Is it a 1 bar tune?

 

Sounds a bit low, but each dyno is different / conditions at time of dyno. For comaprison - my '03 996TT on a Mystang Dyno is (at the wheels):
459 hp
531 torque

Calculate drivetrain loss of say 23% to get crank numbers (so somewhere @595hp/688torque) - give or take as it is not an exact science.

But I have:
zero clearance 16/24 hybrid turbos
Ported/polished headers
200 cell Exhaust
EVO intake
EPL tune


I did see a past post where they compared a stock 996TT to an EPL flash only...numbers were:
375hp / 327 tq = stock
474hp / 409 tq = EPL tune only
again, conditions may vary
So yes, yours appears low

 

Just for reference, my car on a tune and exhaust made 432/430 on a dynojet.

 

Those numbers definitely sound low. Those are more like stock numbers.

Where did you come up with the 23% figure? That's very high to use for drivetrain loss. 15% is more like it for most AWD cars, with maybe 17-18% being on the high side. 10-15% is pretty standard for a FWD or RWD car, with somewhere in the middle of that range being normal.

 

That's an estimate based on various sources..meaning "I don't know". This is one of those elusive topics that go on forever. I'd prefer to leave it at that.

The experts may have better conflicting answers

 

JatDiesel from this board has a stock k16 with FVD exhaust.
I have a UMW flash. We raced and it was neck and neck, me pulling by about 2 cars from 35-150.

It made me realized that a flash was not ALL that. Exhaust on a k16 gives you sound and just as fast as a flashed car. This outcome made me get an exhaust.

 

was this at wicked CAS ? i hung arround waiting but it was getting late so i took off

they didnt seem to have adequate cooling imo, i only saw 2 smallish fans and it was a warm day, i don think anyone got the numbers they wanted/expected

 

Those numbers appear low for ANY dyno of a flashed 996 turbo. However, it all depends on what the car made STOCK on that SAME dyno. If you didn't baseline the car on that SAME dyno, this thread is a waste.
My car made around 338hp/370tq on EPL's Mustang Dyno stock, and 425/500 with a flash and exhaust.

 

There are multiple variables at play here. What type of dynamometer was used? What was the correction factor? Was a baseline run performed? etc...

Mainly what are your feelings on how it's running in comparison to before the flash?

 

Is your car stick or auto ???

 

Yes it was at wicked on saturday. It a stick.
