Dyno Sheets for the Benz

[my1stgn]

Here are the Dyno sheets from Mary's Benz. The stock run was with car running at normal temp, reg 91 octane and some drop in K&N filters. Thats pretty much it. The "tuned" dyno is exactly the same but after a dyno tune from EuroCharged Performance. Over 120 lb*ft of torque just off of a tune!

That'll get it!

Why is the power spiking and dropping off so fast? Usually when you use mph/power you see a much flatter hp graph. Looks like it's not happy around 115-125mph. What trans ratio was this test done in?
