tuning box from tdi tuning

[chimo]

Hi anyone tried a tuning box from these guys? They are selling them for 75 quid on ebay. They say its got a processor in it with maps and they are not like the boxes with resistors. Im looking for one for my a4 tdi 130bhp.

TDI tuning do some proper tuning boxes which plug into the fuel rail that cost well over £300, but the £75 version basically does what the cheap resistor boxes do (fooling the ECU that the engine is cooler than it actually is), but using a microprocessor with variable settings instead. My advice is steer clear, if you want to go the tuning box route get a decent one that plugs into the fuel rail.

I had one on my old A4 from TDI Tuning, was quite smokey when driven hard. Torque low down was better though.

I had two different boxes on AWX engine. Ended up paying 250 for proper tune in Corby and never looked back.
