Hi, i'm not sure where is best to put this but this sub section seems to be appropriate.
I bought my 2005 330ci about a month ago and within the first couple of weeks i took it to BWtune. I was expecting a bit of an increase and an increase in throttle response to match. The car was booked in for a Saturday morning and due to me getting the wrong address i arrived a bit late which to their credit they didn't seem too bothered about! The service i received from Jason and his family/mechanics was fantastic. I could ask them any question about my car and an informative answer would be produced (as it was a new car and my first BMW there was a few!)
The car was put on the dyno and checked to see what it was producing. It was slightly down on power as you can see from the graph below, this wasn't too much of a shock to me considering the age and i thought it was quite normal. After downloading the ECU file and going away to tweak it, the new map was applied to my car. Once the transfer was complete more dyno runs were performed with the best shown below, myself and even Jason were surprised by the results. His comment was he hadn't seen this much gain out of a 330 before and i was very happy seeing a 20hp gain along with a fairly high increase in torque! This could have been down to the fact it was down on power to begin with or errors etc but still it was an impressive result.
I then took the car for a quick test drive around where the garage is located and immediately noticed a difference. After using it for a couple of weeks and allowing the ECU to adapt I can say I am over the moon with the results. There is a noticeable increase in power and when i put my foot on the throttle there is an almost immediate response compared to how it was originally. I would gladly make the same purchase in the future and if i buy another BMW it will certainly be making a trip to Jason and his team. Value for money is excellent.
Once again thank you very much and here are the results:
