Nick,VW Bora 1.9TDI 115

I?m really pleased with the Boras performance since you worked your magic. 283 lb/ft of peak torque and minimum 234 lb/ft (the standard spec peak) available between 1700 and 3200 RPM has transformed the drive. The motorway overtake manoeuvre is now: let the car pass by, accelerate (in 6th) and pull out - oh and then brake to avoid running into back of the car that has just overtaken me :) Well pleased. We have a trip to Lindisfarne next week in Northumberland and en route there are a few longish A road climbs where it should excel. I?ll keep you posted about my MPG. Follow up email, received 23rd October 2007: Hi Dan, I thought I would give you an update. The Bora performed extremely well enroute to Holy Island up in Northumberland. It was always good on hills, but now they cease to exist!. I think the fuel consumption remains as good as it was before the Tunit was fitted, 61 MPG on the trip covering the 200 miles in 210 minutes with a full load and a tide to catch avoid gives little cause for complaint! My perception is that 4th gear now accelerates the way 3rd used to do and 6th in turn accelerates like 5th did. But of course has a much wider range which is redoubled because the torque hangs in much longer. Imagine if it had a seven speed box. I would also like to thank you again for the excellent & conscientious service you provided.

Rohit ,Honda Civic 1.7 d

The honda 1.7 is a good standard car but no guts. With the ever increasing fuel costs i took the plunge and purchase a tunit with a view to reduce costs on fuel. the end result never looked backed. The car has driving characteristics are so much better. Mid range is fantastic. Bigger cars are so surprised.
