    To be fair, the pre-lci didn't have the N63TU so it was down 45HP and 30lb-ft but that doesn't seem like enough to make up for the weight difference of the X5.

    Same trap speed and 3 tenths quicker in the 1/4 mile than the 1,000lb lighter pre-lci 550i. Something doesn't seem right...

    there is a thread on n54tech about stacking with Dinan. There are a few guys doing it, nothing 'officially sanctioned' from what I saw.

    Golf tee mod won't work - the flaps are opposite on the 550 and need to be forced to stay open mechanically. Or you can buy one of these: http://www.exhaustmeister.com/

    Car is quick for relatively minor mods. Why is there such a big difference between 4th and 5th gear pulls? I've heard of differences due to the gear ratio being closer to 1:1 but that seems like an...

    Another interesting dyno - Active were advertising 40hp gains with dps and exhaust, no tune here:...

    Very nice gains...

    IIRC another member (@jimefam maybe?) showed significant HP losses on the dyno by adding catless dps without a tune. Power picked up when tuned - I wonder if that's what's going...

    Do you have a baseline? Any idea why the curve is so wavy down low and up top?

    I wonder if there would be any measurable benefit on the N63, as when the car is under load the turbos are sucking air into the engine with more force than an increased 'ram air' effect would have...

    At the very least I'd have them note it on the service paperwork. That way it will be in their records if it happens again and you need to have it addressed. Sounds paranoids but I've had SAs leave...

    Makes sense - does Stage 1 actively remap/adjust the timing (e.g. CPS offsetting) or is it changed by the DME reacting to other inputs that are changed?

    Here's what Dinan stage 2 looks like:
