TDI Tuning Box

[McLovinH]

Bought one of these 2nd hand, but no instructions, easy enough to fit. But are there any adjustments on these units or is it all of nothing?

Fitted onto a Veccy CDTI 150, thanks in advance

What type of box did you get ?. If it's a t tuning box aka caterman it's a fixed setting.

Iv got a tdi-tuning box on my car and there is a little screw inside which is accessable from a tiny hole on the back of the box which can be turned clockwise to up the boost and vice versa. It comes from the factory set in the middle but turning the screw will feel endless, just do 2 turns at a time until ur happy with the power and ur not blowing out too much black smoke behind!

With the Tuning Box, K&N Panel Filter and Air Box Mod my Veccy was rolling roaded at 185bhp, all smiles m8!

Ah will check it out in a second, K&N Panel filter will be ordered soon, air box mod done too. Thanks for that guys!!

And.....did it work? Just remember how many times u turn the screw so that if u ever want to return it back to standard ull know how many u did!

[McLovinH]

Just a half turn of the screw at a time young man otherwise ull get sh*t loads of black smoke out the back end which is un-burnt fuel and such a waste of money lol, iv turned mine 3 full revolutions in all!
