M5 with just a 30% increase would go from 460whp to 600whp.

And my jb4 tuned n54 had one issue after another. It's a domino effect. My dinan tuned e46 had a major problem and BMW said bye bye warranty when the flatbed showed up at the dealership... So did dinan. Now, try this tune with a $100k plus car, BMW will say 👎 for even an oil change. I still want it 😜 ... But the rims are hideously late 80s 😱

I think G Power stands for God's Power because that's about how much power that m5 has got!

You make it sound like you're Michael Schumacher (7 time F1 world champion) and 640HP is not enough for your level of racing\driving experience.. Don't kid yourself

Bravo G-power! This thing is truly a beast! I can't wait to get the new M6!

That's some ghetto wheels right there. What a shame doing this to a new M5.

[TotalPower]

is gpower the company that has been grenading cylinders in their FI m3's? I remember reading about that.

Reliability will clearly be an issue when heat comes into play....then again, if you have 80+ k and you're spending another couple grand on it then a new block or tranny really aren't an issue and having that sick ass car is just a sweet toy.

+1.

Impressive numbers but i never understood the point of giving the car more power to make it faster and then slowing it down with big heavy wheels.

Lots of haters here!

I just look back at all G-power has done and think its a little premature to speak negatively about them.

Getrag specifies a 700 Nm maximum for the DSC transmission, and G-Power has blown the lid off that number!

Congratulations G-power! Especially considering you did absolutely nothing to beef-up the transmission to handle your extra torque.

As an engineer, I can say there's not much worse than getting someone to buy something because you blew away the stock specification, but didn't bother to tell them that you blew away the reliability as well.

Easy there. You take risks period when adding mods to perfectly normal car from factory. With the E60, most opt for aftermarket springs, add wider tires, add tune, change exhaust, raise s85 rev limit to 8500rpm, etc. Nothing new here so a risk is a risk and we know from history, German engineering always put conservative limits for specs.

I suspect Gpower tune limits a lot of that tq hitting the high values for sustained period on the gearbox. Will it reduce DCT life..sure but the advantage of having more tq and hp will always outweigh killing DCT..at least until we see a few grenade from aftermarket tunes. How bad could it be anyway? SMG in my factory spec car died 20k so nothing we are not used to

I await what our friends at Dinan have to offer.

SMG/DCT replacement will run around $40K. Hey, if you're willing to throw that kind of money away, then go for it!. I've had it completely redone (under warranty) on my E60 at 22K miles. I also had the POS defective Dinan differential replaced at 54,000 miles because they didn't fully seat the Pinion gear. Eventually just wore away the teeth, then broke. No warranty though, since it went 54K miles.

I'll be interested to see what the G-power 'warranty' is. If G-power has done anything to relieve the stress on the DCT, they didn't say so. I suspect they haven't done a thing.
