Is there no write up on what to expect from each different size Injector.? If not why isn't there one would be very helpful. I searched and no go.

 

Get Fuel Injector Clinic, ASNU or Injector Dynamics injectors. Everyone else doesn't use the good Bosch cores and they simply don't drive or tune as well.

Stay away from-
Fuel Injector Connection (So, make sure if you're ordering "FIC" that they are Fuel Injector Clinic)
Fuel Injector Development (they use bosch, but just don't tune well)
Deatschwerks anything

 

I ment to say difference between the sizes and what to expect.

 

I'm not sure what you're asking. You purchase the injector size that will support the power your setup should make. IE- For E85- stock turbo gets 1000cc, ~500-550whp gets 1300's. 600-650whp gets 1650's, and 650+ gets 2000's. And of course you'll need the appropriate fuel pump and fuel system setup to go along with the power goals.

Fuel injector clinic has a chart for all their injectors shows the approximate power they'll support.

 

talking about rough idle, afr etc what to expect not all injector will be the same. Cause my id2000 on 91 pump on cold start the afr goes 10.6 or so to 16-18.

 

So your car has a problem and you're on here fishing for general information? Why would you not just ask that question in the first place...

Sounds like a tune issue. 2000's generally aren't great, especially on pump and if you have stock cams. But it should idle better than that.

 

and that's why I'm asking what to expect for different size injectors lol

 

so which injectors should I get that are not rough and are like stock feel. Plan on going flex fuel down the road only want max 500hp to wheels. If id2000 are rough like this and not so great on 91 pump I need to take them out and retune then.

 

As stated before. You purchase injectors for your power goal, and then put up with whatever quirks they have because they supply the needed fuel.

The ID1300's idle and drive nicely when properly tuned. "like stock" is a bit of a push though they are very good with a proper tune.

 

and id2000 are rough? I did pop a code p0134 and I just replaced the front o2 sensor and got the same code again. I'm coming to the conclusion that's the issue. Why would I get the same code on a new 02 sensor
