here is a shot of my X50 log with Forge IC and 2 1/2 Exhaust. Top of 4th at Laguna Seca running 100 race gas. Looks like the turbos could be pushing more with the waste gate duty cycle at 92%
3) Gear driven>>3 and 4 vs 4 and 5th gear vs 5th and 6th...
4) One can run the boost request higher when running race gas.
Once one see 90% duty on the N75 the turbochargers are near peak output.. One can see that in the early RPM showing turbo lag and then up top in the RPM range.. The K16 compressor wheel will struggle to keep 1bar to 7K... Logging these values will show you what really is happening (general comment to Rennlisters)...
I heard conflicting things, but, as the car is plenty fast, I drive it a lot (10k miles a year), it has higher mileage (126k) and I want it to last forever, I decided to return it to stock.
Kevin was helpful. Thanks.
The fact that Softronic doesn't maintain a log of the VINs they've flashed strikes me as both convenient for them and poor customer service.
With the tune, I did a number of pulls and spiked as high as 1.3 bar and stayed at 1.1 or 1.2 when accelerating.
My local dealer charged me an hour to take the 1.2 bar tune off.
Notice acceleration isn't quite as violent, but I'm sure I'll get used to it.

those numbers on a stock car at the least suggest a vac leak? since an untuned k16(?) car shouldn't boost that high; only .7 with spikes to maybe .8.
e.g. a 1.2 tune would only see *spikes* of 1.3 provided all was was "tight". even if you have a k24 equipped car? those numbers you related after flashing back to *stock* are high EVEN for a stock mapped k24 car. let alone a k16.

I put things in the wrong order. Those numbers were BEFORE the tune was removed.
