ITS got plenty of fuel a 255 wlboro fp and a safc to tune it ive messed with the safc in any way imaginable and it still runs the same but its like im always on the rich side and if i lean it out it still does the same when i hook the maual boost controller back up on the wastegate it only allows the turbo to get 9-10 psi and it wont allow me to go up on boost or down with the manual BC but the only thing i could think of is that the wastegate is getting stuck , my spark plugs do need to be changed but the car seems fine when driving and idle , i do have a very hard to notice hairline crack in exhaust housing but nothing major you could barley notice it
