Are your part throttle AFRs in the 14.7-15.5 area?

 

Bump

 

Yes, when cruising, Tom and I talked, I am going speed density in the spring larger injectors do have some oddities with a pull through maf design.

 

I'm on SD, I just installed a new treadstone 340lph. And it's still all over place. Hopefully the injectors make AFRs spot on!!! Should be here tomorrow!

 

Do people get better mpg with high impedence or no?

 

MPG depends on the tune. But the reviews on these injectors I read make the car feel like stock, I'm also battling a poor fuel mileage fight. Look in my stats for my thread called poor fuel mileage. I'm hoping these help with that issue.

 

The FIC 1100cc injectors are great. I'm sure they will work well for you.

Have you looked into other mechanical issues that may be causing your poor gas mileage?

 

I've looked alot of places for the fuel mileage issue. I'm open to suggestions or ideas, please let me know

 

Take a look at this checklist.

Usually we find that boost leaks, improperly gapped spark plugs, bad fuel injector seals, or leaking throttle body shaft seals are the most common issues.

 

I'm gapped to .022 no boost leaks, done multiple tests. Spayed everything with soapy water. Any other ideas? Thank you very much for your help

 

How did you perform the boost leak test?

 

Took the intake off the turbo, plugged the bleed line off the Grimm speed. Put the car at TDC. Set my air compressor regulator at 25psi. Started at the j pipe followed and sprayed every connection up to the IM then did all vacuum lines, BOV, injector seals on the IM. After that I disconnect the air comp. wait about 2 mins and see if it is still holding pressure. ( it is )

I think that's right....

Anybody else have expienrce FIC 1100 high z ?

 

Well I got them in.

Only issue I'm having is cold starts. It was 23F this morning and it didn't want to start. The tuner got the cruise and part throttle dialed in it seems. Just got to work out the cold starts now :/ hopefully I hear back soon from him.
