"performance' injectors?

[Guest 007]

Have seen the pages like http://www.tdtuning.com/ and wonder if these 'performance' injectors actually do much.
If all else is the same, my driving & habits, will I see..

1. more miles per gallon of fuel used?
2. more usable highway power?

They sound nice but is there a real improvement one can see and feel?

I haven't had any experience with them. I know that installing them will be harder than you think as they're only selling the nozzles, so you'll have to rebuild your injectors yourself, and without some specific know how and tools it's impossible.

I use the same kind of nozzles too.

They are for TDi aren't they?
Is yours a TD? if so then use GTD injectors, or get your's redone with GTD nozzles.

Here is a first hand impression on the GTD nozzles:

The nozzles have a bigger "hole" so you can inject more fuel in less time, theoraticly it should perform better because it will deliver the amount of fuel closer to the timing spec. When injecting more fuel with small injectors it will cause too retarded timing = smoke and less power.

I suspect the stock AAZ injectors are too small cause when I turn up the fuel 0.25/0.5 turn the power increase is very noticable, but idle is at 1500rpm.

I have a set of complete GTD injectors on my shelf, when I'm done with the things I'm working on now I'm going to try the nozzles in my 2 spring AAZ bodies or with the 1 spring GTD bodies.
