Only way to really know is do a 60-130 draggy run. Cause unless the conditions were exactly the same for that stock CS It would be comparible but I’m guessing it’s not since weather air density and all that comes into play

I have the stage 1 tune from carbahn and have been extremely happy with the performance change. The dyno plots they provide on the website indicate peak power to be 642. They do not indicate which dyno they used. Because the variance in dynos I've always preferred to test stock and then with tune - same dyno same day. Then evaluate the difference rather than the how big the number is. Stage 1 should give a gain of about 60HP on pump gas. Does your car feel any different from stock? IF you have to think about then something in your flash isn't right - stage 1 is huge difference over the stock car.

Carbhan in San Jose did my actual flash If that's relevant.

So basically, you had your M5C flashed with Carbahn Stage 1 but you didnt dyno it before the ECU tuning?

So, 664RWHP is what it is but you dont have the numbers of how much HP it added?

Dragy before and after tune is the best way to see the difference.

What was the outcome of your tune with Carbahn?

I had it done, but never got around to doing before and after Dyno runs (too lazy… lol)

It subjectively “feels” faster to my butt dyno. I’m planning to do a 60-130 run with a friend that has a LCI M5 and see wutz up.

664 whp is solid ! that's 784 to the motor... not sure why you feel your numbers are low.
