Vito 109
Anyone who owns a 109 Vito van should get one of these, easiest thing to fit and adjust and the results are great. My loaded work van is a full gear better up hills and economy is pretty much the same over cosistanly travelled roads. Great product and would recommend to anyone.

Huge difference in performance
I have just bought a newer shape shogun after 7 old type 2001-2006 models,and have just fitted a unit, I did a before and after comparison, before the box was fitted it was showing 17 mpg towing a 750kg trailer,and about 15 mpg loaded with a car,with the pro-bitz box and with a 4 turn adjustment,it went to 26 mpg unloaded and 21 mpg loaded! the performance was instantly more responsive,even the engine note has changed,its really made a difference! i am so impressed i have just ordered a box for our bmw 530d estate 2004 model,as it is quite thirsty around town,and the box will pay for itself in 2 months! plus bags more performance!...its easy to fit and foolproof! and Im a car dealer! that says it all!

Mercedes C320
Finally! The installation is the same with the C320 Merc, power gain, smoothness is across the low power revs, what amazes me is the fuel Economy that I never experienced before, now I can do 7.8litres to 100km! Thanks!

BMW 320 CD
Recently I purchased & fitted my tuning chip module with easy installation to my 2005 BMW 320 cd manual Msport. Took her for a test drive & was hugely impressed with 1. Superior acceleration in 1st 2nd 3rd with much more power up through 4th 5th & even 6th gear 2. Zero turbo lag now as there was before 3. Noticeable increased torque 4. Engine runs much smoother now 5. Increased fuel economy.. up to 15% I can't recommend the Pro-bitz tunning chip enough & Andrew's customer service is 100%. It's well worth spending a few quid for one of these top quality chips.Cheers!

Amazing ++++
Being completely sceptical about engine chips and having surfed the owners' forums for hours on end, I spent weeks deliberating this purchase for my 2005 Kia Sportage XS 2.0 CRDI Automatic and finally took the plunge late on Thursay night. It arrived this morning (Monday) and I fitted it this evening. I'm a complete no-hoper when it comes to cars and engines but, with the help of the downloaded manual, had it fitted in about 30 minutes. I gingerly gunned the ignition and, (there being no bangs or explosions!) ventured out onto the open road. Engine management light extinguished after about 5 minutes and the difference was remarkable. Sluggish, tractor-like performance normally experienced whilst pulling out onto the local bypass had disappeared and it felt like a 'normal' car - no more lag at low rpm and acceleration response was excellent. I felt like I could even overtake something - probably a first in this practical but previously unexciting 4 x 4. I'll have to wait and see whether the fuel economy aspect has improved but will report back in a week or two. Thank you
