Need some assistance in making the GSX faster

[ZigsGSX97]

Ok, so I got back yesterday from the dyno at 264 awhp (not happy but not mad either). I've reached my goal, which was to have a fmic, evo III turbo, and 550 cc inj. Well, the power is nice right now and it pulls hard, but not hard enough. My new goal is to make 350-375 awhp, and this is where i need some help. I'm getting cams in about a month, so that'll put me close to 300 awhp. I'm probably going to need a walbro 255, 660+ injectors, and new intake pipe. What turbo would bolt right up to the sbr cast mani and doesn't take too long to spool up? I've got it for the most part, so if anyone has any other ideas or suggestions, let me know. Thanks guys!

You should be able to reach your goal with the evoIII turbo.

I don't think you will need a new intake pipe (which won't much if any power) or cams at this stage yet.

You listed your mods, but how is your tune right now? Do you have any logs of timing and AFR?

What boost are you running at?

We need more information before making additional suggestions.

first of all, hold up on that 255. You'll be fine on the 190 assuming you have the re-wire mod. Any search on here will tell you that. I'm assuming you got 93 octane gas in illinois, which would then lead me to believe that you tuning just needs some tweaking. I maxed out my 550's at about 1.1 bar, but I'm from california. That gave me about 265 to the wheels. So hope on the engine tuning forum for about a month, which is what I did to see if you can lean it up a bit. Post some logs...the guys will help you out.

yea its all about tunining really, i didnt read your profile so im not sure everything you got, but just make sure you have a safc and datalogger, and raise the boost to a safe level, ( dont know how much your pushing now) umm make sure your exhaust system is the best you can do. Maybe even a lightwt flywheel and removal of balance shaft will net you maybe 10 more to the wheels bbut just stick to tuning and turbo boost for now, cams arent as nesscariy, maybe you could consider cam gears though.

I do have an safc 2 and i got it tuned at AMS. They tuned it perfectly (as good as it's gonna get). I'm running 19 psi, and I don't have the rewire mod (HOWEVER, i do already have the wire run from the pump to the battery; it's just not connected yet). I don't have the log of my tune
