D,Kia Sorento 2.5

On the 5th December 2006 I had a Tunit V-CR fitted to my Kia Sorento 2.5. I thought you would be interested to get some feedback on the change in performance before and after its fitting. The car is more lively with a better take-off from standstill and when overtaking vehicles at high speeds. Towing my caravan requires less throttle and again pulling away from standstill is much improved. These observations are, of course, subjective but I have also measured the mpg of the Kia solo and towing. When driving solo on local and longer trips I originally achieved 32-33 mpg. After the conversion I now get 36 mpg! This is excellent. Even better is the towing improvement. Before the conversion I got 22 mpg and after the Tunit was fitted I now get 26 mpg. Thanks also for the Millers fuel additive and the allowance for the K&N filter I already had. This has been one of the best investments I have made. I wish yourself and the staff a happy New Year and all the best for the future.

Peter,Peugeot 407 2.2 HDI

I bought a Tunit unit for my 2.2l Peugeot 407SW and had it fitted and tweaked by Engine Tuners in Plymouth (and what a helpful, enthusiastic and friendly bunch they are!) Over my first 500 miles of motoring, 300 mixed and 200 towing a 1.5t caravan my computer tells me I'm getting 39.8mpg. Previous consumption without towing was 42mpg at best so I'm pretty pleased with the result. As for the improvement in power and torque, quite frankly I'm not so young as I was and I find it quite scary!

Thanks guys.
