Went on a spirited drive today and notice when going through the gears it held back at high revs almost like flat spot or fuel cutting. No lights came on and otherwise was normal. I’d probably say that the flat spots were intermittent too. Anyone have any ideas where I should look first? The plugs are probably less than 800 miles old so doubt its them. Only mods on the car (performance wise) is decats, cobra back box and silicone intake elbow.
