I'm slowly working on my car. Have it running well & most of the maintenance items taken care of. Currently running 10lbs with a hallman pro, 2.5" cat back, & a single pop. I have a jdm tt swap so it's peppy with the na rear end. Trying to decide what to do next. Either downpipes/test pipes, intercoolers, or a sz tune & more boost. I plan on doing all 3 but at intervals so what do you suggest next? Some say do all the support mods before more boost, others say the opposite. The tune is definitely the easiest of the three.
