I know it's expensive, but...

Hi folks here,
Regards on tuning my 650 gc, I have contact with pp-performance. Some folks here might hear the brand before. When I drove my old x6 I admired them so much because they tuned world's fastest x6m.
Ok... I just received reply from tgeir customer service and told by them the ecu of my vehicle is impossible to tune instead they can send me brand new 2 motor ecu+CAS ecu. It's directly plug and play. The output of it will be 510 hp(stock was 450 hp) and the torque will be increased fron 650 Nm to 730 Nm. Max speed will also been increased fron 250km/hr to 300 km/hr. 0 to 100km acceleration will changed from 4.5 seconds to 3.9 seconds. The price will be 3899 euro.
Do you guys think these improvements can lead to 0.6 seconds faster than stock?
Is it worth to purchase it?

First, are you tracking your GC?

Second, even if you are tracking your GC, some better brakes, stickier set of rubbers, a suspension swap, etc. are probably better mods than getting an ECU upgrade.

It's not something I would care for, but if those numbers are actually true than the price doesn't seem that bad. I am very hesitant to believe those numbers though.

Yep, I also think is the numbers are exactly true then the price will not look so bad. Just feel your mind I am also very hesitant to believe the numbers. The improvements of torque and horse powers seem can be achieved, but the 100Nm and 60HP power increasing can make the car go faster 0.6 seconds. I doubt it. The audi RS6 with 560hp and 515 torque also just can reach 100 km/hr at the same time.

very rarely, but that's just me even it's a DD, I always want to make it has monster power.

Exceeding 500HP on this engine will be commonplace very soon. The N54 crowd can push those numbers already.

Yeo I hope so, but is the valvetronic in this engine is similar with n55 instead of n54?

N55 has one turbo, N54 has two, like ours - that was the basis for my comparison.

Yep... thanks man if the engine set up of our engine is really similar with the n54 then we can expect a huge gaining from tune..
