if you use crome pro with itb tools 06 then you should be able to tune it just fine. i'm using crome pro and tuned mine without too many problems - daily driven too!

but i agree, leave it to the pro's if you don't know wtf you are doing as far as tuning goes.....

the best setup is itb's and a plenum box so you can take advantage of the helmolz (sp?)resonance.

But h22's don't have as many options as say bseries, so this is definitely a low cost alternative... for bseries, something popular right now is the importbuilders modded itr intake manifold..... definitely affordable compared to itb's.
