Nice! I've been eyeing EcuTek for a while. Who's the dealer/tuner up there?Took the car into my tuner yesterday. I am moving from BM3 to ECUTek, and he is still dialing in the wastegate control. Update this morning says he made ~360 whp targeting 15 PSI (tapering slightly to redline). ECUTek is really robust software and I should have full boost control available through the steering controls or my phone, down to the PSI. Excited to have her back today or tomorrow.

I'm doing a bit of R&D help for both this tuner, as well as ECUTek themselves. But they recently released S55/N55 support to their tuning suite, including an addition called "RaceROM" which allows on the fly map switching, peak torque control, custom functions that the tuner can write, flex-fuel sensor integration (which I will likely eventually do, need a fuel pump upgrade first though).Damn, freaking impressive! Loving the idea of an SUV that hauls ass and is tuneable.
I don't see BMW on the EcuTek site, is this a BETA test?
The tuner is Dave Bigley at Cryotune Performance, and he's a really great dude who has no problem getting into and explaining the details to customers. After my call back tonight, he says he reached 364WHP targeting 15PSI, which is more than Bootmod3 was getting targeting 17PSI (350WHP on the same dyno, not same day).Nice!

A ton is probably an overstatement. You can't really tell the difference in peak torque, and the area under the curve everywhere else matters more. Bootmod3 might be able to achieve a high number, but as soon as the car overboosts, throttle cuts and the entire car shudders. At that point WGDC is so conservative that it can't catch back up. Keep in mind this was the stage 2 map for the stock turbo, the Stage 2H was even worse, and that's supposed to fit the turbo better.If I'm reading that right, you lost a ton of torque because of the throttle closure and that's delaying getting into the power band by about 700 RPM and 40whp. I'd say your car on the BM3 tune would put a car and half on you by then, versus your EcuTek tune and that the current EcuTek tune would have had a hard time making it up on the top end, even with the extra 10-15whp above 5500.
As far as tuning, without logs to review, it's hard to say, but it's either hitting one of the limiters or he can try changing the pre-throttle over boost tolerance limit or major throttle closure threshold tables. Not sure what those are in EcuTek speak. The table names differ some between BM3 and EcuTek.
