done some reading on the forum and came to this conclusion.. please correct me if im wrong..

I got giacced today and got a K&N filter. the boost is great but the boost seems to stotter sometimes coming up.. from what i understand is that the diverter stock valve needs to be replaced with a better one..

am i correct..? should this fix the stotter in the boost? before getting giacced i had no stotter.

Thanks for teh info!!

I'd say it'll be wise to upgrade to a better one anyways.

But I have a GIAC too, and i still experience surging/stuttering. Hours of forum searches and crap says i have a boost leak, or its the MAF, or the O2 sensors or something else. I'm just say thats how GIAC is (perhaps) shrug. BTW Don't quote me on anything.

a) replace all the small vac lines in the engine bay
b) get a boost gauge
c) get at least the TT diverter valve

Go from there. Do them all at once, probably cost you $80 for a decent boost gauge, vac lines and the valve, and 2 hours of your time. After that there's all sorts of miscellaneous hoses and crap you might need to replace, but a boost gauge is a must after you chip.

I would also change your plugs... I would rather go with plugs than a new DV for shuddering...
