New and need some serious help

[Twenty8]

so i contacted brookdale mitsu to just get a full overlook of the car and just get everything checked out. I currently dont drive it at all because my parents are so scared to let me drive it. The mechanic just sounded like he just didnt like the whole idea of a modded car and so i just think he really didnt have a clue. i currently have a pressure gauge in there and it does work and it kind of seems like i may be running at about a 10 on the gauge but i dont watch it everytime i shift. Im really hoping its just the coils cause that is way less then we were told.
