contemplating my first move on my first supra help!

[gersain]

ok so i pick up a 1990 mkiii 7mgte the guy i bought it from said i needed a cam position sensor and a map pressure sensor for it to run fine but i call bs this guy never cleaned the car and overall was a sloppy owner the piping wasnt even attached and he said that it had just came loose that day. so after i tried connecting it i realized that this idiot did some horrible fabrication and cut a pipe 3-4 inches small. after i realized this i kinda figured that the cam pos sensor is good and maybe the afm is bad but im not sure whether to fix the piping or buy the afm and my boost gauge works since it moves from -4 to 0

i need help with deciding what to do next the afm or the piping thanks in advance :3d_frown:

You need to do the AFM *and* the piping. The AFM won't matter if the piping isn't connected since the metered air will be escaping anyways.
