    I apologize for not getting dynos done sooner. A lot of crazy stuff has happened in real-life, some really good and some really bad. I'll keep it short for now, but there's very few people I've...

    This isn't true. On a given engine, boost at a specific rpm DOES dictate airflow because the engine's profile is generally static. But if you add something like downpipes into the mix; then you've...

    You have to understand that boost is the BYPRODUCT of the engine not being able to 'ingest' the full amount of air being shoved into it; it is NOT the result. An engine that can flow more air will...

    No that's not how it works. As has been said, it's about increasing airflow. You can have two motors with the same turbos making the same boost, but if one of the motors flows much better, it will...

    The dynos on this site generally use STD correction, which reads a bit higher than SAE correction. However, it's not THAT drastic. Definitely not exaggerated as its much harder to cheat on a dynojet...

    Yeah, imagine the forum vendors are better at dealing with your broken forum than you are (memory leaks, broken notification system, garbage performance on android chrome, etc) ;)

    Thanks man. And don't think I blame your or your company at all. I get post notifications for plenty of other threads but not this one :/

    It may not mean much but I keep that value as stock on my dct Z4. There is a post $#@! timing drop on 2-3 and it takes a good 1k rpm or so to fully recover. It does so gradually. I wonder if those...

    Once again, bimmerboost fails. I did NOT receive a notification that this thread had been updated. That cost me $100 at least. And i hope the response for a total price from the poster in this thread...

    Torque curves do change with rpm, but the multiplication does NOT change. What changes the multiplier is the effective gear ratio.

    Average power to the ground had already gotten to the ground.

    Thats not how it works. The torque multiplication is great but it's still irrelevant. Average power to the ground is what controls the overall acceleration of a car. Torque multiplication isn't...

    The run you supplied looks as to be expected on map 1. You've got zero control on the boost signal meaning it's going to follow a natural curve based on how much air the motor is able to move by rpm....

    It barely flows more than stock for one thing. I think the stock Z4 pump flows as much or more than that pump. Why would you use it? If you do a search on the various single turbo builds on this...

    Superior gear spacing effectively increases average power. The MT vs DCT comparisons on the E9X M3 are a perfect example. By adding more gears and not being stupid about it, they're getting superior...

    I don't think I'm going to get much out of retuning it at this point. I may tweak the timing further and take a look at the vanos tables. But I don't want to push TOO far as the DCT clutches are the...

    ETs aren't an indicator of speed, but that australian car amply demonstrated that transmission options are what holds the platform back regarding ETs.
