I need some help for tune ups because of mods. For those of you who are already experienced in tuning and modding the MSP, what should i be doing as of now? I've been focusing on maintenance only for the past few months. I currently have a FMIC, stock turbo, and catback. I haven't really had time to install a boost gauge and air/fuel ratio gauge since i'm so darn busy. I would like a bigger turbo but don't really know the difference between the gt28's. I would like some guidance and advices from all the experienced members.
Thanks
