You said you had a street port, pfc, large single turbo, 550/1600 injectors, and all the other bolt ons
I took the "all the other bolts ons" to include an ignition amp. I run one for added safety. What kind of boost are you running? Do you have ignition break up at higher rpms? What plug wires are you running? I run taylor plug wires, they were like 35 bucks. Stock are probably fine but I'd replace them with something if they are old and/or have high milage.

a few of the things i think i have left to upgrade are pulleys and ignition stuff. I have stock plug wires atm, but when i change plugs i plan on getting new wires. Im thinking of getting the NGK plug wires, any opinions on them? Are there any differences between the makes of plug wires at all??? Right now im running .5 bar, once all tuned and done i want my high boost to be 1 bar. Hmmm.... define ignition breakup? My current issue only happens in here in reno, nv - not at sear level (in Ca) It has a slight hesitation at once i get into boost, if not full throttle. It seems very strange. So would there be a big difference between the 9's/10's???

I can't comment on the difference between 9's and 10's. I was running 9's before I got tuned. Also I just had a new engine put in. I switched to 10's just before pulling on the dyno. I've been happy so far and I don't have any plans to switch back. Either one should be ok if you are going to stay at 15psi or below.
As far as needed an ingition amp, you might want to try new plugs and wires first. Maybe then check the grounds on the car. After that if you still have a little shudder at higher rpms then I'd get an ignition amp. I bought my HKS twin power before I started running above 10psi. I just wanted to be over prepared... I've not had any other plug wires than the taylors so I'm not too sure on which is best. I've been happy with mine so far but it's probably just whatever you like the best.

Thanks for the info. Im going to try the 10s i believe, as it seems that bigger is better in the case w/ the single turbo. I will find out about the ignition amp when i go to get tuned. Yea, my high boost will definitally be under 15 psi. Any idea on the sizes of the plug wires your running? Does a mm here or there make a big difference?

My plug wires are 8mm. I bought them from summit racing for under $40 if I remember correctly.
Remember you'll have to have the tip of the spark plug socket cut down to get the 10's in the housing. Here is a picture of one:

So 8mm would be more then enough for 10's? hmmm.... where would i go to get a socket cut down, or better ? - where could i get a socket pre cut down ??? Thanks again!!!

.022 gap? is that the rule of thumb? I cut down my own socket. It was a decent craftsman socket. It's garbage now, the chinese factory contracted by craftsman didn't cut the hex on centre, so when I cut down the socket one side of the wall is paper thin... and the other is thick. And this was the only awy to get it to fit. Then i broke the socket. if you are going to cut it down on a lathe, get a nice expensive socket, not made in taiwan/china craftsman tools. Lately i've noticed craftsman tools with made in taiwan sticker on them. i"ve replaced one of my phillips made in taiwan screw drivers 5 times now because the head is too soft and easily gets damaged.
done rant.
