I've only ever felt this lugging in 4th gear, intown. It was down to about 1200rpm and it felt a little shaky. The tranny didn't downshift, and it only lasted 2-3 second.

I wish I had the money to upgrade my turbo. Hell, I wish I had the money to buy the $90 injector nozzles I want.

My cheap tuning box / glorified Every Mod type costs $35 on eBay , I put a link but noticed the prices are higher now.
http://www.ebay.com/itm/Tuning-Chip-...f116b7&vxp=mtr
Tuning Chip Box Volkswagen Golf IV 1 9 TDI 90 110 PS More Power Powerbox Diesel | eBay

If I turn the set screw clockwise 2.5 revolutions from its stock position the car is peppy / fast throttle response. but if I turn the set screw 1/4 more of a turn the exhausts starts smoking soot. So I keep it turned down to +2.5 turns from stock.
This little cheap tuning box works !

I may get that sometime. This weekend I'm going to order a Vagcom from newegg. Maybe if I'm lucky I'll get my new nozzles next month.

Cool

That sure beats the hell out of twisting set screws on the injector pump.

Its convenient to use as it plugs inline with the factory connectors.
Having the set screw makes it more useful as you can tune it to your car.
Some people might leave is set smokey so they can be special(lol) and get noticed
or is it go faster , I'm not sure what the point is.

Also this cheap type of tuning box does not work well on gasoline motors ,the results would be disappointing.

Once a diesel starts to smoke, you still get performance gains, but they start to drop off fast. You need something extra like propane or NOS to go with the extra fuel to keep the power coming.

Well I finally broke down and bought the parts I wanted. Bought .216 injector nozzles, the in-line tuner that you suggested, a new timing belt, and a VagCom

Sweet , I think you will see about a 50hp gain , I'm not actually sure what hp the .216 do over the stock .185 , the tuning box will work good with them.
