Loss of Power on Dyno
I am struggling with a loss of power issue on my prepared auto-xer. An NA with streetport. At the last auto-x, the launch find then I hit 2nd, and the engine started missing, like short of fuel, then it would catch a bit, but continue to run poorly at 1/2 to open throttle.
Out of drive, the engine revs freely and sounds correct, no back fires, rough running, car starts right up. The power loss appears only under load.
I put it a dyno and checked A/F ratio looks fine. However, I am losing sigificant power (only 130 rwhp).
I am going to check fuel pressue. I am also going to check spark. How does one check spark? Any other ideas to check?
Thanks
