Just because you have a block guard doesnt meen you can run mega boost, but 450 ish is the most I would do.... But the turbo you have probably wont make more than that....NEITHER WILL the 450 cc DSM INJECTORS... which will yield maybe, 300 whp before being completely useless.....

My only question to you is why buy all these nice parts, and then get 50$ injectors?
