Had a chance to dyno my car for the first time.
This is with my exhaust from Pushkin & stock everything else
The exhaust is 3" straight pipe into 135i muffler. Should be equal to a n55 midpipe & 135i muffler fitted to n52 exhaust manifold
It was a hot day,but compares to be about 10 Whp below an e90 328 Xi that has AA tune and DISA manifold.
Im putting down about 210 Whp for 91 Octane
Temperature: 27-28 °C at noon outdoors, 50% humidity, perhaps warmer indoors
Enjoy the graph and data. STD Smoothing 5
UPDATE Jan 2013
Dyno with DISA & No Tune!!!!
Same as before: no secondary car & no resonator exhaust into 135i stock muffler
DISCLAMER: Using 94 Octane from PetroCanada, 17" Winter wheels, 225 tyres
Temperature: 10:30AM -3 °C& 80% humidity outside, perhaps around 5 °C indoors

UPDATE Confessions of 2013
EVOLVE Dyno!! with issues :S
Confessions first.
N52 Gods I hid the truth, I must repent. My sin is that I had no time to do a proper dyno that would compare Evolve to all the other tuner dyno's which usually have an Intake.
What did I hide:
I do have a dyno of Evolve on the day after the flash for my 128i which I haven't posted because I felt it was not an ideal dyno because it was so soon after the flash and it didn’t highlight the Evolve’s commitment to the tune (offerign service to tweak the file if needed, especially if I could get a diagnostic file created and so on).
At the time I just didn’t think it would be fair, it was big news, and I was waiting to do a dyno pull again when the same shop offered a discount dyno day in the summer months.
I consider it a rather poor dyno for a few reasons listed below:
- My goal to dyno was just to see if the investment actually worked, and I didnt spend money for nothing. Dyno was on the next day after flash + 150km drive on mixed roads. Car did feel good the previous night on backroads, I felt it adapted. I was wrong it was mostly the throttle remap.
Therefore, the car is in the late adaptation period
Overall, the tune works and fixed the dips in this dyno.
- Wrong Fuel. I had “94” octane Petro Canada/Sunoco, since then I discovered that 91 octane Shell Vpower is the best for the tune and it makes the car feel different, more aggressive. “94” was used to be consistent with previous dyno’s.
- Evolve’s tune for me was tweaked for UK 95 RON/ Canada 91-93 AKI octane. I have only Petro “94” or Shell 91 here. This is NOT the USA’s 93 AKI/UK 99 RON. Therefore, the dyno’s fom UK in theory, are better than my result. I actually prefer Sell’s gas cuz its cheaper, so win win.
- No Euro-Box installed in my car. A severe bottleneck, esp the 4 month old filter and Charcoal filter intact. The Eurobox + dry AFe did, for me at least, feel like the last touch that allowed the car to breathe, equalize the decat in my exhaust and the more open intake, and it felt like a mini 3stage manifold all over again or at least a new flash of the tune. Despite critics, I do think the Intake helped me gain a few hp and TQ and I made sure to plug my ears to ignore the sound changes (actually, it made the exhaust quieter and I had more wheel spin/traction loss).
- Oil change. I was past the middle of my cycle, the oil was the same as the previous dyno of the 3 stage manifold just 3 weeks of driving 200 km round trips for at least 3x a week+ weekend drives around the city easily being 200km.
- This dyno has no comparison to other tunes. I could not compare my car to Evolve’s dyno and the German’s claiming 270 PS/265hp for a 125i. My goal at the time was to redyno with Eurobox to make objective comparisons against these idol’s including the AA tune which is usually dyno’d with the Perf Intake and with 93 octane. Also, I was still on winter 17’s, the same ones I had on the 3 stage Manifold dyno, and I wanted to a dyno on my 18’s and compare it to the my base dyno.
So in conclusion, my car had a bottleneck and the wrong fuel therefore the tune is not represented well.
I believe, that the final gain over the Manifold with the tune + intake is similar to Desi4Life’s e90 328ix’s complete AA tune dyno gain over No tune ( He has PE &Perf intake ). We did use the same Dynojet shop.

The intake I guess would put me in SAE at ~220 whp and 210 wtq OR in STD ~228 whp and 215wtq and not the numbers you see below... :S
So apologies in advance, I just wasn’t able to redyno the way I wanted to make it a proper comparison.
I do love the tune and feel it does what it should now that it has adapted to the intake: the acceleration is smooth and aggressive past 3k rpm. Very refined, perhaps more than others based on their dyno's having blips.
I have no regrets and have a path for headers
