I have 2 Tunit plug and play units .
The first is for a VAG 1.9 tdi 90 or 110 using a VP44 pump and the 10 pin connection . You tube this ,, Skoda Octavia.1.9tdi was 110bhp now 210bhp .I did a bit moe to it than just chipped it though . Ditching the EGR and cat on a 110bhp should get about 140 bhp and a proporsional increase in torque . Offers over 100 quidit was 300 new .
The second is for a Fiat JTD or Vauxhall cdti or Saab cdti . It was fitted to my 2006 2.8 jtd motorhome , my daughters 2005 1.3 cdti corsa and my 2012 1.3cdti corsa . Performance was up quite a bit .MPG stayed about the same as you tend to use the extra oomph . The motorhome went from 22mpg to 28 mpg though as I didn't need to row it through the gears all the time Offers around 175 quid
