Just got it back from extreme performance here in az. I'm no expert or even experienced in dynos and stuff. The power is great but I'm no fan of the roush calibration. Throttle response has lag that I can't stand. Don't know the air fuel ratio or boost. Getting another run once I get the gauge. Not sure why the lines are squiggled but in guessing it's the roush calibration. Any input is appreciated. This is the 575 hp kit.

 

Did you regap the plugs? Looks a little like spark blow out. Of course the Roush tune for emissions has to be tame so it could be low timing numbers as well. Either way it doesn't look bad and those are great numbers!

Thanks, Doug

 

those are great numbers for their conservative tune. Probably spot on when they say 575. Engine bay looks sick man! Good Luck


what should engine life be like with this kit if you dont really use and abuse it? someone said about 40,000 miles and the engine will be ready for rebuild?????

 

 

The numbers should be in SAE, not STD, STD just inflates the results.
Next why do they have the smoothing at 3, set it at 5.
