That 100-110....woof

Car keeled over and died.

View attachment 259690

90-100 mph 1.57s
100-110 mph 2.44s
110-120 mph 1.88s

Linear interpolating between the 90-100mph and 110-120mph elapsed times we'd expect something like 1.73sec for 100-110mph. I'm doing this on mobile so feel free to check my math ➗

I'm unfamiliar with DSG but could a shift around 100mph really put the RPMs into a low boost range of the power band?? Not sure what could've happened there.

Edit: in spite of that, that's a pretty damn good pull comparing with times listed in post #9 here. If it weren't for the weirdly long time spent between 100-110, you'd be sub-11, maybe around 10.8.

Coulda just been a dragy screw up. I’ve seen it give wonky data before when it loses satellites.
Yikes. I have no idea how it would take 2.5 secs to get from 100-110, good catch.

Either a Dragy-aneurism or DSG/TCU tune irregularity. It’s usually 2-flat or 1.9 seconds.

Edit: Some old times showing my typical 100-110.

No idea how it could drop by .5s without me feeling something, must’ve been a satellite thing. Who knows, maybe it has more in it after all.

100-110 = 1.95s

Some EQT news I stumbled upon just now. Interesting to see how this tune/IS38+/stock downpipe will compare to the DTR/tune, even though I have an R.

Nice. More companies developing options with the stock dp, the better IMO. And IS38 upgrade on otherwise stock hardware is exactly the route I would be interested in going.

Pay to be a test subject. Tune should be free IMO.

We have offered this for roughly 7 years if memory serves correctly.

I’m on DQ250 - can confirm, shifts around 105 WOT in Sport.

I really need to get a logging solution.

Yep! It’s on my shortlist, especially since I’m already an APR tune customer 👍

According to support you don't have a stock downpipe is38 for my 2020 mk7.5. Already went down this path and was turned around.
Yeah, I've looked into it previously as well and saw this on the site and always assumed it required a downpipe as part of the "exhaust system." Probably my fault for quickly assuming, but I've still got life left in my IS20 until I need to actually research haha.

From the product page:
"This simple upgrade requires an IS38 drop-in turbocharger, an exhaust system, intake, intercooler, and no other engine hardware modifications..."

It would be wise for APR to clarify what "an exhaust system" means, but APR has told me before that it doesn't require a DP.
