If I end up doing any porting, it will be just to flow more, not to try to eliminate the boost creep. ;) If the creeping bothers you turn the boost down and let it creep to what you'd have it set at in the 1st place. :P

That's all, just a S-AFC to tune it?

And yes Jeff, I did read, note that I said I read most go with 660's. 550's are good for ~22psi, possibly a little more according to RRE. I wasn't asking what supporting mods I will need, I just wanted to know what the stockers were good for and what everybody used to tune.

And for the supporting mods:

ported Evo exhaust mani
ported Evo o2 housing
3" turbo back
fmic w/short piping
rewired 255lph fp
and maybe a GM maf w/ maft

I read 660's are pretty much the end of the line for the S-AFC, is that right?
