Even if the absolute numbers might be slightly optimistic, there’s not much doubt that the gains are impressive and real. Some Dragy runs would be interesting.
Given what I’ve seen from testing in Europe with multiple cars and multiple dynos, you can use a 911 in standard form to calibrate a dyno rather than the other way round: you know a 911T will produce 370hp at the crank +/- a few hp as that is what Porsche have programmed it to do whatever altitude or temperature you’re at...

Yep, I have one too. It’s not that I think my car is special but rather the point that it’s not a single back room shop dyno that is measuring these cars higher than the manufacturer is advertising. In you initial post you mentioned that the specific dyno was optimistic. I simply pointed out that Ray’s results were in line with many other base C2 results. These were conducted at various locations, using different brand of dynos, by different back room shops and in various regions on the country.
The T is special but the numbers are the numbers.

a believer that the dyno is over reading for sure. When wheel power is around the same as manufacturer quoted (and measured using proper standards) crank power then I have no idea why the dyno owner would believe it was accurate.
that said the delta is a real delta so that is all good!
Porsche probably uses SAE measurements - this dyno is using STD Smoothing 5 which will yield a higher number. That's what most dyno shops use that I've seen.
For those who don't know, most shops will give you the ".DRF" file from a Dynojet after your pulls. You then go and download WinPEP7 (it's free) and you can then over-analyze that run file using all the different measuring standards. Trust me, I know lol
I've found STD numbers are about 3% higher than SAE. That's not a scientific study... just what I've noticed on my Mustang.
Also, Dynos aren't meant for racing just for testing. The track tells the whole truth.

So..
1. What happened after the other mods?
2. Did you get any errors?
3. Did you switch to "dyno mode"?
Looking forward to more pulls

havent had a chance to install the bypass pipes yet. Hopefully within the next few weeks.
2. Did you get any errors?
no issues, warning lights or errors so far at all. I have put well over 1000 miles on the OTS stage 1 tune so far.
3. Did you switch to "dyno mode"?
no sir, just disabled traction control and let her rip in 4th gear!

TC off (hold down for 2+ seconds) and Sport plus for me. No issues other than a bunch of lights coming on during the dyno (ABS, Traction control, etc). Once off the dyno and driven around the block, the lights self cleared once the car sensed all wheels were moving at the same time.
