Boosted Performance round 2 list

See I dont know why the discrepancy vs what I am seeing then. I know on my particular car when Specialty Z was tuning it they had to stop because it was leaning out up top. Now that issue seems to have went away with a fuel pump relay, but still the loss I see in the fuel system is significant.

Are you watching your fuel pressure at all during this? I would have to go dig through my text books or google on the relationship between flow, size, and pressure but I would say just off the top that your 1000's at 65% would probably equate to somewhere around 90-100% with the 750s. I believe the relationship between injector size and flow is exponential. Again id have to do some digging to confirm.

Maybe this information is just becoming available through testing we have seen in the recent weeks. But I cant see why most of you didn't opt for the larger injectors for $150 (or so) more. You would have all the fuel you would need on stock numbers for the easiest way possible. This eliminates the need for a RFS which costs 3X more with the same simplicity as what you had already done.

If I were looking to get another 2psi out of my edged out pump gas setup, I would just sell those 750's on the market, buy 1000's, and you will have all you need. I am shooting for 11psi in the near future and from the data Iv'e collected I wouldn't need to upgrade a thing. All while consuming 30% more fuel.

I most likely will get a RFS and go for more power but I wont leave E85. The smell alone is worth it.
