Great news! Your Accessport have been used on my previous cars (EVO X and GT-R) and it was just amazing. Very easy to install, not expensive and very effective! Waiting for your Stage 2 solution with sport cat. Thank you for your efforts to make us more happy.

Any news?

BUMP. When and where can I get one. I had one on my STI's in the day. They worked great.

Any updates?

I'm waiting for their 991.2 Base tune......

Others are already offering tunes but none with something similar to Accessport.

COBB Tuning

No firm updates as of yet, unfortunately. The guys are still plugging away on both the 991.2 and the 718 ECUs and they're making some decent progress. As soon as we have some firm info on ETAs, we'll be letting everyone know.

Thanks!

These things take time.

Was the 991.1 base run at the same time on the same dyno?

Because the 991.2S makes around 360 at the wheels.

Porsche have already produced a Power Kit for the 991.2S - complete with new factory tune, full exhaust, two new turbos and a full Porsche warranty

This will give you 550Nm and 450HP (peak) and as power under the curve from 4000rpm to 7500rpm ~ 408HP (and at 4000rpm ~308HP)

its always interesting to ponder the question "what modifications does Porsche suggest and deliver to give a safe, robust and reliable outcome"

Its one of the great internet myths that Porsche understate HP - they don't

Ah - ok, got it, bumped graveyard thread

Is there any updates on this?

That 991.1 curve seems a bit low to me - was that car healthy? I've seen in other places that the power peak is at 7400 rpm (350 crank hp), which is what Porsche claims as well. Assuming a 15% drivetrain loss, that should put the peak hp at 297.5, presuming 350 peak hp is correct.

There are several searchable dyno pulls out there that have the 991.1 base putting down 308-312 peak wheel hp @7300-7400 rpm, which suggests the 3.4L is making 360-365 hp at the crank in stock trim.

Quibbling aside - there's no question that a 75-100 hp gain to the 991.2 S model is hugely impressive from a smaller engine. Making around 450 hp out of 3.0L is an accomplishment....with more to come from the aftermarket.

15% loss isn't typical anymore. It's more like 8-10%. Transmissions are much more efficient these days. It's pretty unlikely Porsche is sand-bagging the power figures.

Jenner

The loss on a dyno is 15% or greater. I understand what you are saying about the transmission and agree but dyno can be 15-25% depending on dyno type and manufacturer.

For example my local shop uses a Mustang AWD dyno even on RWD cars. This dyno reads lower than a dyno jet. On a RWD car the rear wheels spin both the front & rear rollers. This causes the front wheels to spin which makes all the sensors in modern cars happy. Otherwise if it was RWD only they wouldn't be able to dyno it as the ECU sees the front wheels aren't moving, freaks out and goes into limp mode.

When my GT4 was run on this dyno it equated to a 24% loss.

I am really curious to see the results. It seems that so far only MTM has a tune for the new 3.0 engines and if I remember correctly they are producing an additional 50hp or so.

I think the S can become a solid 500bhp car easily with just the tune. I wont be surprised if the new cars with barely a tune and maybe exhaust run 10s!!!
