Really? Who is tuning your car? Ask them. Also, talk to Brian at BNR. He will tell you exactly what you need. If your tuner specifies something else, go with what your tuner wants. If you are doing the tuning, you should know what your fuel requirements are.

People with stage 1's have dyno'd around 300whp. With a stage 4 he shouldn't have a problem with 350whp+ given that he has a tuned standalone, according to what the BNR site says anyway.

If you're only shooting for 300-350 why are you getting a stage 4?

a bigger turbo isn't better, get one that's properly sized for your desired hp.

you can't do 1680's very well without a standalone that will give you more precise control over injector staging.

I talked to Brian from BNR last week and I was told that 4x720's would be enough for a stage 2. Would it really be enough for a stage 4?
