For starters, I have the star stage 2. No problems so far. Set at 5psi just to be safe.
When I run it at a constant throttle, say 3K in 3rd gear, you can feel the throttle jerk constantly. I watch my gauges (EGT, AFR, boost, and S-AFC) and see nothing that shows what I feel. I changed my plugs today, but no difference. If anyone has any ideas or experience, I'd appreciate a hand here.

Thanks,
matt

can you tell us more about your fueling, what size injectores/fuel pump. also leaky BOV or boost leak somewhere b4 the TB might cause that.

I'm using all the stock stuff w/ the star kit. I have the walbro pump and the vortech 12:1 fpr w/stock injectors,rail, and lines.

I also have the HKS SSBOV. I've tried changing the settings on that to tighten it down. Maybe I need to go a little further.

Thanks for the idea.
