I bought my sc with a 1jz single swap last year and when i would be full thottle it would cut off at 4k i blew that motor up and swapped a 1jz just all stock. Last week it would hit 7k and be fine but now it cuts ou at 2500 smetimes 3000 rpms and i am maybe hitting a pound of boost if i am lucky. I was thinking it could be a fuel cut but my spark plugs are not the best. I know people on here would know what it was more then our mechanics here in minot nd haha.

If you know the plugs are worn, start with that, sound exactly like what many other end up with. Just get some NGK 6097's and gap them down to .28.
