Dinan 627hp & 616lbs m5 tune package

As im looking into the dinan website its says,

+ 627 HP and 616 lb-ft of Torque when combined with the D-Tronics Performance Tuner and exhaust. A difference of 17 HP and 11 lb-ft of torque from Dinan Stage 1 (D-Tronics Performance Tuner Only).

Free Flow Stainless Exhaust (D660-0044 & D660-0044-BLK): An important addition for any enthusiast who wishes their car to sound as good as it performs while also supplying significant power gains itself. These exhausts are dyno tested for maximum exhaust flow with minimum backpressure. The system is designed to provide a more aggressive sound under acceleration, while reducing drone inside the vehicle, thanks to Dinan’s exclusive Helmholtz Chamber and Butterfly Valve technologies.

D-Tronics Performance Tuner: Coming soon. The D-Tronics Performance Tuner is a highly engineered and sophisticated piece of computer hardware and software that enhances engine performance, without negatively affecting new car warranty coverage and without affecting long term reliability or the functionality of on-board diagnostic systems. It was also designed to be emissions legal in 50 states (E.O. Pending). The ultimate objective of developing this piece of technology was to provide the ability to control every signal entering and exiting the BMW factory Engine Control Unit. These items are unique to Dinan and together they embody the apex of performance engineering in a powerful, reliable, and warrantied

I must say 616 lbs of torque on rear wheel drive, youll be fishing all day . I wonder whats the real numbers on a dyno.

I need to see price in order to justify the power gain.

Yup.. That exhaust sounded so bad they took it off the website...

Better doing DPs, RPi, and BMS and saving money.

@///SAL Steve mentioned the tune in his radio interview. Since they have a high level of control over the ecu they can adjust the curves not just add boost along the whole range. So in low gears the tq is saved for the higher end helping to stop fish tailing and keeping power where it needs to be. 616 tq in first would not be good. He says the keep it right at the limit of grip and save the rest of the power where it needs to be.

Can't wait to see if this is reality.

The Dinan is a piggyback right?

I doubt that they have more control over the ECU than what companies like AC Schnitzer has with their piggyback for the M5. And that has been out for years...

And ACS have delimited their cars as well (but hit a second limiter in the transmission set at 320km/h).

But ACS stuff is expensive though...

My experience with Dinan exactly that!
They crank a few ponies and add to the real number vs the underrated number by BMW!!
You are paying for 10-20 more ponies if so as I have seen so many Dyno of bone stock of North of 600 and I remember some 620 too so where is the gain? Torque ?!
Correct me if I'm wrong!!

Dinan non software stuff seem to be of good quality yet overpriced quality! !
But like Thomas "I won't believe till I touch those numbers and way above 650 Crank" to be of real value! ! And still with RWD!! So more for bragging rights !

My thoughts exactly, now if Dinan's numbers are whp, then that would be entirely different story. I also read that this is a piggy back with press tune, but calibrated by Dinan. If they are not tweaking air/fuel and timings this is no better than your already available piggyback tunes out there.

Dinan measures at the wheels from
My understanding.

How is this car's stock 575 hp not enough for you? You do know that 575 is underrated so much that it's usually around 640-660 hp? Do you ever see yourself driving in queens in a situation where you need more horsepower and torque than that?

So a reputable tuner is charging the better part of 10 grand to detune the car by 25ish hp?

As noted above, MAHA whp is c/w factory crank rating assuming 12% DT loss.

Looking forward to seeing trap speeds on a Dinan tuned car.

Is there a release date on the website, I don't remember seeing one?

Here's a Dinan BMW M5 (e60) with a Stroker 5.8l 630hp engine for those interested. It sounds insane in my opinion...
