I just put a 950 H.P. on my car and I have a couple questions. I would like input on a good tuning book or video. I haven't messed with any Holleys before so I need some guidance. The carb seems very responsive and works almost perfectly right out of the box. The one problem I have is, when I run it up against the converter and then floor it, it kinda stutters for awhile before accelerating cleanly. If I step into it more slowly, like when your trying to leave without spining it performs very well with excellent response and power. I went to Holleys website and , if I got this right, think I may need to play with the squirter size. Is this correct? Would it be the primary or secondary squirter that needs attention? Any input would be helpful.

Thanks in advance
