2008 125i  [5.00]
EvolveR tune for 125i

Had the tune done through SouthernBM - thanks Andrew
Before and after Dyno attached - a bit dodgy and out of calibration but the improvement is consistent and significant across the range. Blue is power and green is torque
Conditions similar, if anything, the later dyno was on a hotter day - 18 vs 23deg air temp.
Peak power 121kW vs 96kW
peak torque 2850N vs 2600N
The car has been tested previously at Advan in Sydney and produced 129kW peak power about a year ago.
I have aFe intake and BMW PE exhaust installed.
Personal impressions - not much change at lower rpm, but past 3.5K feels more eager to rev and noticeably faster to pick up speed. Overall the character of the car is slightly more aggressive, but not markedly so unless you flog it mercilessly. I haven't taken the car to the track, but that's where the improvements would show better I guess.
For the cost - $1299 installed - I am actually pretty happy. Over 20% gain and across a decent rev range. For a NA car that's remarkable.

Congrats! Glad you are happy with it. This kind of power increase on a NA car is rare so enjoy.

Awesome stuff. This will be one of the first things I'll be doing when I pick up a 125i.

Now, if only I could find a decent one!

Manual. There's a few nice ones I've seen for sale recently but I'm not into the colours. I'm pretty fussy with what I'm after.

Ideally:
  • Manual
  • M Sport
  • I-Drive
  • Black, White, or Gunmetal
  • Less than 90,000km
  • Less than $40,000

Just a matter of waiting for the right one to come along I think.

Hi morris86 and welcome
I bought a 2010 125i coupe earlier in 2013 with similar criteria to yours, although I wanted low km (<40k). As you may be discovering, there are far fewer MT cars than autos available, so in the end I settled on a non M-sport car (with some regret) as it ticked all the other boxes. Be patient and you will be rewarded
In the meantime, enjoy researching & contemplating possible mods ...

2008 125i  [5.00]
3 month update and re-do Dyno at Advan Performance
Car still feels happier to rev and accelerate compared to before the tune
Fuel consumption unchanged
No engine lights or error codes
Starts as per normal
Overall - very happy
Updated Dyno from Advan below
Blue line before, red line after. Torque and power both show substantial improvement across the range.
Previous max power 129 kW

People in the tuning business will tell you not to look at the top numbers but rather at the area under the curve and consistency of improvement across rev range. Either way its 23% more killer wasps and much more responsive.
From about 3K revs the difference in attitude is noticeable with the seat-of-the-pants dyno
4.5K on - its a different car, almost
no idea what made BMW de-tune 125i compared with 130i....
