Mann, those are monstrous results for the minimal mods that car has! Of course with a tune the boost will be upgraded along with the proper fuel and boost controller. But it's up to the owner if he'd want to but usually the tuner will up the boost as safely as possible. They won't ask you if you want to keep or increase your boost; my tuner didn't ask me, he just did it as safely for the mods I had. But man, those numbers.....especially the torque increase! I underestimated those X's!
