Just got back from the dyno. Check out the graph.

Just got back from Church automotive. I did a baseline run, just to see where i'm at before I install my mrev2 and spacer. Well, the numbers are high due to it being a dynapack. The tuner told me that to get the whp to subtract 8% from the peak hp on the graph. That would put me at 264 whp and 232.4 tq. That still seems kinda high for a stock 06 with pop charger. Also, my engine is running lean in the midrange and running rich up top. The torque seems o be going up and down. Anyone know what that is? IDK, let me know what you guys think.

do you have a after market exhaust? And that tq sure does go up and down what is up with that hopefully some else will chim in.

Its stock with the exception of a pop charger. I too, want to know whats going on with the tq fluctuation.

What tuning are you using? If you have an intake on the stock ECU thats pretty typical of what you'll see as the ECU compensates for what it thinks are errors. The MAF calibrations were put together using the stock intake piping to be as accurate as possible for volume and velocity, change the intake pipe and it goes all out of whack and the ECU does it's best to adjust timing and fuel.

Also as you can see the TQ numbers correspond to the same deviations on the HP numbers. Torque is power, Horsepower is power over time. It's fairly typical, though maybe on the outside edge of typical.

hmm, interesting. I am running the stock ecu.
