It's been done to death, need wire to maf, or generic settings will present and mass overfuelling on overrun/idle

Mine isn't soldered to MAF neither does it over run :nenau
Explain please.

Sorry mate did not understand a word of that, Rick

A tuning box needs a signal from the maf, otherwise it will just dump loads of fuel through out the range, resulting in mass over fueling at idle and on over run

A poster this year posted about a cheap box @ £60 and his over run problems, then his move to the speed chip box that I linked and how the maf signal made so much positive difference

(I hope u are grateful as I just typed all this out on my iPhone after 12 pints and a meet up with a very good mate I've not seen for 3 yrs)

Ta Stinky :thumbs but if you will have an iphone :lol
Adjustment is the key with tuning box. If I turn mine up to the max then yes it will up the revs a bit, but that's operator error. RTFM
They either work by cheating the value from the maf, ie tells the ecu it's cold air, therefore ups the fuel a bit or monitors the pump advance I think.
Either way the ecu is "spoken to" via the loom. Either by the plug n play socket on the engine loom or directly via piggy backs on the earlier models.
Same difference anyway, more fuel earlier = more omph earlier. Makes no difference to top end
