This is meant to be a brief and not all INCLUSIVE over view of Chipping, Injector nozzle air box questions.

Stage I usually refers to a chip upgrade or nozzles only.
Stage II usually refers to chip AND nozzles.
Stage III usually refers to hybred or non-stock turbo, nozzles and chip. .
There are "Custom" programmed chips out now that use a number designation to identify it and it may or may not mean there is a non-stock turbo or nozzles in combination with them.
A boost gauge and Exhaust Temp. Gauge should be installed before any engine modifications. This gives you visible engine health indications and can save alot of heart ache later. It also helps when asking questions in the fourm as you can give data for others with experience to work with.
If you do a web search for "EGT" and diesel, you should find yourself a few vendors selling gauges. If not check the link farther down the page for parts.
Two places you do not really want to waste you money on in increasing your performance of the TDI is putting in a fancy intake system or exhaust system. The word mufflerectomy is used alot and that means the muffler is taken out and the exhaust is run straight. Not to loud for most, your turbo may spool up a little faster with this set up. The filter box gives good performance as it is, some take out the snow screen and some have removed the snorkle. The snow screen being clean or removed makes a good move due to the snorkle picking up cold air from behind the head light. One exception to this might be installing a "Old Man Intake" this may improve air flow to the turbo and has been reported by forum members to help cut down on excesive smoke.
"if you want to order a OMI email send an e-mail to,blubyu@ameritech.net, the price is set at ~$105 shipped in the U.S just tell him if you want it black or grey and with or without the ccv hole. if you have any questions he normally respondeds that day."
The best source for parts is to check the TDI club registerd vendor list and contact them for info and web site or here provided by Blackenedbora. http://forums.tdiclub.com/showflat.php?Cat=0&Board=UBB35&Number=911797

I understand that programmers USUALLY recommend nozzles first over chipping as you may need to chip again if you add nozzles later. The choice is yours to make.
Auto trans guys like me: you have from the factory smaller nozzles than the manual transmission cars and also come with an 11 mm fuel pump.
Manual trans you have from the factory larger nozzles than the automatic transmission cars, some modifiers will up grade to the 11mm pump or use a kit to get more fuel to feed the bigger holed upgraded nozzles since the manual transmission cars do not have the 11mm fuel pump.
Injectors with new nozzles should be pop tested as some may need to be shimmed to make them all work the same. Better to find this out before putting them in. Also they do have a break in period. Make sure you get quality and the proper copper seals to go with the injectors for the install. This will save you some grief later.
Chipping again check the TDI registered vendor list or do a web search. There are quite a few programmers out there now.
Nozzles alone will give a significant performance increase, but not mind bending and in some cases may need some program changes using a Vag-Com. The chip changes the stock program and dials in fuel, boost and some other things, so usually it is the most impressive first up grade. The biggest bang for the buck is a combination of nozzles and chip. What combination is a personal choice and should be discussed either with your nozzle vendor or the chip vendor. Of course the fourm will more than happily voice their oppions.
Finally, auto trans owners, do not worry, the FAQ is conservative in it's nozzle recommendation. I use the .215's with what is considered a stage II chip and my trans has not complained yet. There are beefing up things that should be done to the drive train, but that is another thread.
Manual trans cars should be aware you may experience clutch slippage at some point and the probability increases with more aggressive modding. Which makes sense I hope.
It has been reported by some that upgrading your FMIC helps to cut down turbo lag time and in some cases to nil. EGT also appear to drop significantly, but each will experience their own results based on design and implementation.
YOUR MILE PER GALLON WILL NOT BE AFFECTED BY A CHIP, NOZZLE UP GRADE! Milage is a function of how you drive. When you up grade, the power will over take you
, and the more you stomp the throttle, the more fuel you use. If you drive with sanity
, you will get as good if not better mpg.
Enjoy your TDI, we are a special group, let us enjoy our cars no matter what level of modification you are at.
