Hello... i just put in a stage 2 head with jun 3 cams on a stock gsr shortblock. but for some reason after 2500 Rpm it starts to mis-fire and you could feel this major lag after 2500 Rpm... i changed out the ecu, spark plugs, the dizzy and the wires still it does the same thing. and for some other reason i sounds like there's something in the head like a click or something of the sort. If anyone have any idea please let me know. thank you
