Sarah,Renault Clio

Purchased a Tunit for my Renault Clio in summer 2007. Found the installation easy despite being far from a mechanic! The staff were happy to talk me through any questions I had pre- and post- purchase. Unfortunately I was involved in an RTA in the Clio and have since bought a diesel Leon, which my particular Tunit does not fit. Obviously this is an unforeseen circumstance and I would imagine had I had the luck to continue with the Clio for a long time period as I had expected, the Tunit would have performed exactly as described on the site. I found fuel economy to be only very slightly improved (although I did upgrade to larger alloy wheels around the same time so this would undoubtedly have increased my fuel consumption from the original wheels), and I found a marked improvement in engine performance.

Michael,Skoda Octavia 1.9 Tdi

When I sold my A6 I traded my tunit for one to fit my wife's 1.9 TDi Automatic Skoda Octavia. the installation was straight forward although a little awkward because of the way Skoda clamps the leads. Once installed we started seeing a better than 10% improvement in milage on the VAG 1.9 TDi engine which on a long trip will often show in excess of 50MPG if driven carefully.
