yes, it is recommended that you get a 1.0 PCM w/ a 3.4 pulley. both DHP and ZZP are good manufacturers. i guess it all comes down to personal opinion.

another thing you may want to look into for a cheap and effective mod is a Ubend delete.

oh, and one more thing your gonna want to look into in order to support that 3.4 is a CAI

Re: dhp vs zzp pcm?

Doesn't he have a u-bend delete? And with the Borla CATback exhaust system he has a resonator delete.

For the 3.4" SC pulley I think some more exhaust mods like a bigger down pipe and a hi-flow CAT converter. Also note that he states he has a FWI which last time I checked is a CAI.
