OK, my SR is having a problem from time to time, maybe once every week or two, when I get on it it will just cut out like its hitting fuel cut when I get into boost.

I am running 15lbs, I do not have boost cut, and I think it might be my tps any ideas?

My mods are 550cc injectors, romtune, z32 maf, 255lph fuel pump, s14 t28, fmic, TBE, 1st gen dsm BOV recirc`d if it it helps....
