BR-Performance Stage I M5 F10 + RPi GTM Exhaust + Downpipes

[MCarsFan]

Here are the results of the Stage I remap of my M5F10.

The first 3 pulls were done in 4 th for comparison purposes.

My car is stock Competition Package other than the BR stage I tune.

All runs were done with Shell 91 Octane.

I decided to use EAS to Dyno the car as they are well known and a lot of M5's have been dyno'd there. I felt this would add credibility to the pulls done in terms of the results produced.

Calculating the hp equivalent at the crank (15% higher) would equal the claimed 680hp.

598 / 0.85 = 703 hp using the middle pull result. (thanks to Boss330 for correcting the math!)

No downpipes..

I want to thank Steve for undertaking the Dyno and personally thank Tom, Robert and Kevin for helping to arrange to get the car dyno'd.

EAS is an awesome facility. The team are real professionals who have a deep understanding of what they do.

Nice job bro. And that's w no mods I wonder what the results would be if you had pipes and dp. It's a good thing to see forward progress with these tunes. Hey is that a decible or smog detector they are measuring at the tailpipe?

[MCarsFan]

Not sure boots, maybe emissions? I'm sure someone can tell us.
I think with downpipes, exhaust and air kit the number will be huge. For me, 305's at the back are a must to get the power down.

How does it feel on the street?

I guess they extended the redline in their tune. It does not look like it runs out of turbo, the curve for the 'red line' shows a dip of a ~60hp from 6k to 7k rpm and then a rise of ~30hp to 7500rpm.

It feels great on the street, feels stock when driving smoothly, but when you put your foot down there is an amazing amount of power on tap
Will need wider tires at the back once these ones are torn up though.

Yeah, def need stickier rears, some say 305 is that max, others have put 325s on 20x11s, dunno 4sure if 325s will rub or not....

[MCarsFan]

For now I want to keep my cars 343 rims so I think 305s..Will see when the time comes..

Which rims are you using? Does the top or sidewall rub front or back?

The tube in the tail pipe is to record Air/Fuel ratios

Thanks Kevin.
