You COULD, but A.) The turbo won't even hold close to 15psi by redline. And B.) The turbo is out of it's efficiency around 11psi.

370s will be at 90 percet duty cycle. Not good to push them that far. I would go for some FC or DSM gray top 460s.

have somebody follow you to catch the peices of the T-2-small that fly out of your muffler when you crank it up that high.

i tried to do 14psi on my stocker, it would quickly fall off to 11 by 5500RPM. its not even worth the effort.

I think you mean DSM 'blue top' 450's. Don't forget, the 95-99 DSM injectors work too, but they are black with green pintle caps.

short answer: No.long answer: No, because the turbo won't hold the boost till redline at that boost and you'll be overheating the air. Get a bigger turbo...

im boosting 14-15, 2-3 time a days. Usually my airflow and duty cycle on my multimeter are in the 90% range so i dont keep it too long. Im boosting at 12 13 normally or stock boost in the rain. More than stock boost is pretty slippy in the rain .

You can try at 15 but its not very good due to turbo efficiency maxed out and injectors past their recommended duty cycle..

Do that and you'll be killing mosquitos and glossing-up your engine bay with your expensive oil .
