Dinan for 2014 650xi convertible

[acowanss]

I see endless threads about Dinan kits for this car with lots of commentary about "feeling faster", not "feeling" a difference, questions about performance and results- every time I added an eCU improvement, exhaust / intake mod to motorcycles I took it to a shop with a dyno- I had them dyno the bike before the mods and then dyno it right afterwards- it's black and white- either the upgrades add power or they don't.

Why aren't there simple before and after dyno results being posted for the Dinan and or the Burger kits? If they each really add HP and torque at the rear wheels I'd think everyone would be posting them?

I also question if 15 rear wheel HP / torque is going to be felt by the driver on a 4500 pound car - I'd say not.

Does anyone (other than Dinan or BMS) have definitive, simple dyno results for either of these mods that show they really add meaningful power to the rear wheels?

thanks

Yup. Don't waste your time with Dinan and go with BPM. They are known as one of the best for BMW's with proven results and great customer service.

I have Dinan stage2 on 2012 650 xDrive and can say without a doubt the tune added massive power. No Dyno results as would be tough with all wheel drive.

It supposedly took it me from 400HP/450 torque to 490/579 and I can say it CERTAINLY feels like it. Totally happy with the power and the driveability, I keep asking myself, when I will get a dreaded drivetrain error as the power is stupid. It even know when the oil is cool and will not add too much additional boost until warm, then holy crap. what a tune!

Ok one downside, felt weird going to BMW dealer laying down over $4K and 1/2 hour later the car was done. They should of kept it for at least a day to make me feel better. Seriously though, would highly recommend it but mine is N63 not N63TU motor, your results may differ .

Autocoutoure installed the DME tune on my 2015 Bmw 650 convertible awd. Never did a dyno of before and after but I certainly know there is a ton of extra power. Tested it with numerous vehicles to see the difference. It's treamendous, took few hours to adjust. A+

Does anyone have any experience with Bimmer Performance Center in Raleigh NC. I'm looking for a flash tune for a 650xi.....they are claiming 127 HP increase at the wheels.
