Not everyone is going to use a huge turbo.

Not everyone is going to be using (or even have consistent access to) E85, and if they did, there's a reasonable possibility that 1000cc may be too small for that.

Not everyone wants to purchase and fiddle with adjustable FPRs only to face decreased low speed efficiency and tuning issues, and end up having gained nothing aside from more headaches and expenses, but with no more power.

And lastly but most importantly, while no one's opinion is sovereign above all else, I hardly feel the intelligent advice offered here by amateurs and the experienced alike is "garbage" because it doesn't fit your own plans.

FYI

 

But wouldnt upgrading to bigger injectors cause stability issues. I thought 1000cc injectors needed EMS to run smoothly.

 

I feel ya man. That's why people shouldn't post stuff like this. You're better off a) researching it yourself -- it's not that hard or b) talk to the vendor you're buying it from.
