A good attitude would also be to make a simple rod bearing upgrade to prevent a catastrofic engine failure(IF there's really a chance of a bearing failure)!

AFR's look dangerous. There is much more load on the street than the dyno, fuel pump or injectors are static. I would never run a car like this. Lower boost or upgrade fuel system.

The M3's DME will vary AFR's based on load. When these cars run higher load the DME will add additional fuel. These car's can run high 11's to low 12's at higher RPM and much leaner at lower RPM's but at this power level the stock fuel pump is maxed out when you cross over 7,500 RPM.

I am just talking about the lean condition over 7500rpm. The DME can't add fuel if the pump is maxed and fuel pressure begins to drop.

We limit timing over 7500 RPM in our software, that is why you notice the TQ drop off. Doing this keeps the motor safe even if AFR's run a little leaner as the motor get's to 8k and above. Technically with our software anything below 13.5 at high RPM's is safe. The only time this would be an issue is if we were forcing timing up top which we do not do.

It was a great time last week Scott and awesome power! I'm glad we were able to make some runs before the night was over. I wish David and Shawn (spelling?) were able to dyno theirs too.

^ ^ good to know Roman as mine leaned out a little at the top end on the dyno as well. But not enough to cause any concern.

Well, now I know what it takes to get 600 wheel....gotta upgrade to a 650 kit. Nice job 1SickM !

The DME is adapting. The dyno is not a "normal" experience for it

I did about 25 pulls 5 different dyno days before my car had 1,000 miles on it and there was a massive difference between pull 1 and pull 2. It would max by pull 3 or 4.

Now I don't get such a large delta when I dyno for some reason like I did when the car was newer.

FYI, the graph that has HP, TRQ, FP, and IAT- the line plots for HP and torque should be swapped.

Amazing how stable the IATs are on the dyno when you introduce meth.
