an SAFC and a set of injectors.
and how did you tune with a datalogger? it dose'nt tune,and you have no other tuning equiptment,atleast not listed.

Or MAFT and injectors.

But he does have a MBC........

Get a SAFC2 or and MAFT.

Get a intake hard pipe from dejon, good investment.

Get a S-AFC II, MAFT, intake hard pipe from dejon, and an upgraded clutch. You will need that soon enough.

One thing I was never really concerned with is suspension. Well let me just say, it will change the whole nature of YOUR beast when you can get that power to the ground constantly. Traction is your and my enemy, the gst severely needs a great suspension. If you are stock like your profile says, you need some wider tires, stiffer springs/shocks. I suggest something adj. so you do not have a terrible ride with NO way to adjust it to your satisfaction!

I felt the immediate difference when I got a good tire and a wider contact patch.

Good luck!!

thanks midnght and raytsi, like ray said, i used the data logger to watch for knock with the higher boost and to see if my throttle position was good (recently port and polished head). i forgot to mention i have '17s on with azenis 225. thats the first thing i did to the car since crashing my SR20det 240 due very shitty rubber...sigh. i'm getting a used 2g MAS with hard intake/KN this weekend so i'm excited for that. once i change my rotors i'll be sure to get some motor mounts in. thanks for your time and help, have a great weekend!
