I'm trying to decide which injector nozzles to upgrade to. I recently replaced my mk4 jetta alh turbo to a stage 1, I'm planning to straight pipe it soon, and then will eventually get a custom tune on it by a local shop. I've been reading that some nozzles might smoke more than others or that I might need to upgrade my clutch when I upgrade the nozzles. Any recommendations on nozzles that wont smoke much and won't tank the mpgs much? Thanks

Buy as big as you can. Throw in an 11mm IP, too.
The more fuel that can be injected, the shorter the injection window can be set, maximizing both potential power and economy.

(Implied in the first couple sentences is "consult @burpod for your tune, too - he's got this stuff figured out way better than the "big" names you've probably heard of before.)

More than I need, less than I want
Choose your tuner first. Let your tuner make the decision what hardware based on what you expect out of the modifications. If the tuner is indeed custom dialing your software, they will have strong opinions on what hardware they want to work with. If they don't care, that might not be a good sign as far as your choice of tuners.

To this point, if you can buy a Stage 3 "INSTAntly available TUNE", regardless of whether your car is running .216 nozzles and 10mm IP or .232 injectors and 11mm IP....you can rest assured that neither of those setups will get an optimally-optimized tune.
