If you vent the tank you can see readings like this:What exactly do you mean by that?

I am vented, and I fill my tank slowly to prevent foaming. I filled up last night. I'm now at 28 mpg. I believe my injectors are all messed up. I'll be having them looked at soon.If you vent the tank you can see readings like this:
Franko6 says the numbers, for best fuel economy, should be within 0.20 of each other. I pulled my injectors and dropped them off at the post office. I'll follow up when I get them back and see how it performs.Nero, I'm getting 28-32 mpg (in the city) on my wagon with a stage 4 tune, same as you. VW's spec says the injector balance should be +2.0 to -2.0 of each other and you are well within that. Here are my injector balance #s:
.24,.38,.-19,-.45 (at idle)
.56,.59,-.52,-.66 (at 1500 rpm)
You are COMPLAINING about being 1/4 tank down at 405 miles?I am vented, and I fill my tank slowly to prevent foaming. I filled up last night. I'm now at 28 mpg. I believe my injectors are all messed up. I'll be having them looked at soon.
I would be curious to what your IQ deviation will be when you get them back from Frank. When I put my DLC 520s in I was told that the IQ deviation didn't have to be 0.20 from each other because our single pump controls the injection for all 4 injectors, so they won't be the same. Our pumps are not a common rail system and that is why the numbers will be off. I don't how much truth there is to that because that is more than my knowledge base. I believe the last time I checked my numbers wereFranko6 says the numbers, for best fuel economy, should be within 0.20 of each other. I pulled my injectors and dropped them off at the post office.

On another note, they were pretty clean still for only having 3k miles on them.

Anyone else want to chime in on this?
I'll chime. Frank has forgotten more about this than I'll ever know. But I'm not buying 0.2 as a maximum optimal rage, more like 2.0 max is what most report. The spec says -2 to 2 that's a spread of 4. Rarely do we see that much.Franko6 says the numbers, for best fuel economy, should be within 0.20 of each other....................snip..............
I've seen folks report readings beyond 2, rare.To reiterate, yes max spec may be +/- 2.0, but that's the max I've ever seen them go. I believe that's the full range of control the pump has. Frank said my #3 was running at -1.85 while the rest were within +/-0.20 after making repairs, As Frank put it, my #3 was over fueling to the point of melting pistons if I drove it spirited all the time. Luckily I didn't. I should be getting my injectors on Sunday. I so can't wait to get my car back.
Glad to hear that you are back up and running! Yeah that parking brake can really affect your mpg not to mention the wear on that rotor.Well, day 3 is about to start with the injectors in. So far, Sunday and Monday, tons of power, and no more white smoke. Even if I really goose the heck out of it, all I get is a small poof of black at initial throttle and that's all. What a tremendous difference. Found I have a park brake that's not fully releasing, I'll address it then fill up to see what the fuel eco is. On another note, tried calling Kerma about the injectors being as messed up as they were. It didn't go well.
Which car was this?Well this is a first! About an hours worth of driving, half city half freeway. Helped a friend move. Also fixed the stuck caliper today, and tomorrow new tires. So I'll fill up after the tires are put on and run the tank out, and report back. But so far it looks promising!
My 2003 jetta wagon.Which car was this?
Where can i get one of these?
