As you can see, using the SAE CF, the 335i dyno'd at 302 HP @ 5800 ft altitude. That's more than ANY stock 335i. I think that proves without a doubt that the SAE Correction Factors are way off and should not be used for forced inducted cars.

OK, but if we use uncorrected numbers even for a stock car...thats like 300whp. How can it be that much? That means like 350 at the crank

How do you figure that? I believe you're looking at the wrong graph.

Stock 335i is 242whp and 335xi is 224whp

No, I was referring to the general public that usually dynos around 270-280 SAE. Uncorrected would mean about 300whp.

Guys, I have all the real data, before and after Dinan, and uncorrected numbers on the Dyno. I will post a full review by tomorrow morning with everything.

I know I'm probably starting to sound like a broken record at this point, but what you want to get your hands on is your DRF (dyno run file) file from Nick @ MAC AutoSport. Ask him to email it to you.

I got the files - what do you want to know? Uncorrected hp was about 235. Been working mostly with Clay at MAC.

My stock 335 made 279whp. But that was at sea level, 45 degrees.

What mods in addition to the rev 1 flash? Exhaust also modified? Can't wait to see you results!

Can you please post up the uncorrected graph?

Huh? The correction factor depends on altitude, humidity, temp, etc. For general public, most are near sea level, so the CF would be in the low single digit percents.

Depending on weather, it could be at zero. Look at Shiv's dynos. He posts both SAE and uncorrected and they are within a few hp.

Only at altitude does the correction factor really skew the numbers. Just because you have a high correction factor at altitude doesn't mean that is the same correction factor at sea level.

Ok, something isn't right. You said uncorrected is 235 and the graph you posted shows uncorrected at 265. Was that a typo?
