Here's my car's attempt to draw table mountain with a power curve:

Tbh ignoring peak figures that's a strong graph. Strong midrange torque and a nice plateau of power. An intake would give you a nice result

Cheers. The car certainly drives fine and checking through my VCDS logs I can't find anything wrong. No problem with boost, N75 duty cycle, missfires, temperatures..... Mechanically I'm not aware of any issues.
The only thing I can imagine is that a new filter is required, as currently fitted is an 18 month old GSF paper item. In the interests of science I'll change it and see what happens on VCDS g/s logs at the high end.
I wonder why mine made a 300lbft (very much transient) peak every time, yet the other K03 cars from memory were lower and flatter from 3000-4500rpm. How odd.

It is an 07MY car with a BWA engine.
May I enquire what the early gearboxes do differently to newer models?
The rolling road lark is good for generating thought even if the absolute numbers should be treated with caution. :happy2:
chungster:
^^^^^ this is my old 06 BWA GTI with Revo S1
SteveP:
And here's my graph with the AFR plot
and Torque
RedRobin:
.
My numbers were well down from the previous two JKM Dyno-Day sessions: From around 269 bhp to 244 bhp and the torque max down about 5 ftlb, but the curves okay. Air-Fuel Ratio plot was erratic and was beginning to get slightly erratic on my previous session last October.
I've always said that apart from the social and fun aspects of a Dyno-Day meet, it's a very important opportunity to check the health of your car. It's also partly why I always go to JKM - For consistency and because they know my car so well.
I'm not going to try and guess what's wrong but the worst case might be valves. The next move is to revisit JKM and for Jim to do some logs and then we'll take it from there.
The car drives well and performs and responds well too on the road, so no obvious signs of a fault.

This aimed at my pic Sy???Have an ITG fitted which is about 4 months old.Twintercooler is now on, and need the map tweaked to suit, but Jim at JKM didn't have time today.

Just seemed strange that power dropped off after 5500rpm so steeply id have expected it to level if until 6500-6900rpm. Even more so if you have an intake and intercooler.
That said everones seems to be doing the same as well today so ignore me

Here's my graph from last time, when my earlier map was changed to Revo stg1 and the ITG was fitted. You can see how much my car liked the viezu map :confused:
From comparing from graph from yesterday to the above, i can see & understand what you're saying. Car doesn't feel any different to drive though.
Jim's comments on yesterday was that the car is running great, but map needs tweaking to accommodate the twintercooler.
