Tuning?

[ts_MKIII]

What would you guys prefer for a tuning item:

like SAFC and why would you use that, what are some good things etc let me know what you guys think,

ALSO what exactly does the greddy profec do?

 

[robbo185]

greddy profecs are boost controllers

if you want something that tunes good....get maft pro...replaces safc and lexus afm...but make sure you get 550's if you are looking to tune for more power
