I went to a local dyno day and put it on the rollers I had the free spartan ultra comp on it It did 359.8 hp no torque cause it had no pickup. i think uncorrected can't really figure it out if it was or not i am hopping not, It was a dynojet. the operator said he couldn't get a good graph cause he had to run it in OD did like 130 mph. It was only me and a 12v (368 hp wned )that were there for the diesels rest were gas jobs. was hopping for more most say 400hp with the sct so maybe i will have to call eric at ID and get his tune.
