The Tunit II has provided reliable performance tuning to electronically controlled injection systems since 1998. Adjustment and setup is simple via a screw on the body or visit one of our dealers for an install. Performance and economy gains are seen immediately. Drive is easier and smoother.
The Tunit II focuses on reducing the lag seen on older diesel engines. Mid-range improved torque makes driving much more of a pleasure bringing benefits in economy also.
The Tunit II is adjustable on installation. If the vehicle has a change of use then further adjustments can be made.
The Tunit has provided economy for many years on an array of applications and has been used extensively on Military vehicles.

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.

Just a quick feed-back for you following the fitment of your Tunit module fitted to my Mazda CX7 last Monday. On the drive from home to your establishment I averaged @42 mpg. Following the installation, on the drive from you to my mothers home I averaged 52 mpg! On the 200 mile drive from my mothers to my home I averaged 52 mpg! No flook then!! As indicated on the day, the car does run much smoother and the pickup and throttle response are much better. Great job guys, I shall be towing with the car soon so shall let you know how that goes also. Many thanks, Keith.
