Upsolute is the only chip running company in the US I guess, there's not too many bolt ons for these cars, the common mod is to install a 14t from the t4 model and remove the cat

You can remove the main cat and weld a straight 2.75" pipe you just need this welded or threaded to that pipe:https://www.ebay.com/itm/121904567355 

so you don't get any CEL

Check engine light lol sorry

 

so i just welded in some pipe in place of that front resonator. weird thing is was that there wasnt a cat in front of it someone had already welded this weird little glass pack in there so i just left it. but now im trying to figure out what i can do to make a little more power.

Nope, you just need to install a boost gauge to keep an eye on the increments and ideally a wideband gauge so you can keep an eye on afr's as well, yours being an early 2.0t can take more beat than the phase 2, it can take around 300hp obviously with supporting mods and correct afr's at wot

Like Rick said get a boost gauge and you can turn the boost up the couple lbs your looking for, I laid everything out for you on volvospeed, I'm ol' dirty noodle, something happened to my account here and my name got changed to this number
