test runs and some loading up questions?? Turbo guys?
72 Nova 5.3L w/ GT45 , 317 heads bowl ported, 224/224 .580/.580 112 cam, 60# injectors, 8.6:1 compression, edelbrock int, custom intake elbow, TH350 w/ TCI SSF, 3.50 gears. 15# of boost, HPTuners tuned w/ wideband by myself.
I an hold the brake spool it up and it comes off the line pretty crazy. Once it gets going it just feels as if it loads up and doesnt pull as hard, coming off the line it tachs up fast runs super smooth and is awsome. As its going it sounds like its sputtering or random misfireing. I thought the plugs might be shot but not.
My A/F is a consistent 11.4-11.6 under boost. Timing at 15*. Making a full pass last night IAT hit a max of 105*. I pulled the plugs out today and they look brand new. Everything seems fine?? Anything Im overlooking? or any Ideas?

Im trying to get my belt to stay on right now. But with this cam and injectors the gas pedal feels mushy, like its not very responsive. idling and driving around it doesnt mis at all. There is a idle issue also, it sometimes fluctuates between 500rpms and 1000rpms going up and down.
