CR Tech 2 - BMW X3 3.0d Tuning Chip
Really easy to fit with enough lead wire to have options on where to mount the box. I left it set at the default setting & so far I am very impressed. The first highway trip had fuel usage in the lower to mid 6L/100km range (2005 alloy block single turbo 3L X3) . Map 1 gives a much better driving range than the original BMW settings, I felt I was using much less throttle in normal suburban driving & the fuel consumption indicated this too. Really good value for money purchase & will pay for its self over time on fuel savings. I would & have recommended CR Tech to a few people already.
Bluespark Pro - BMW 320d 2009 Tuning Box
"I had bought cheaper alternatives for my previous car which was a VW Golf 2.0GT TDI and they were awful. I was therefore not expecting much for my money. First of all the installation is very easy indeed. The car was a 177bhp BMW 320d and was ok but a wee bit sluggish. I took the car out for a 10 mile drive to test the Bluespark Pro and I could have driven it for 1000 miles. Its astonishing. Im at 220bhp now with similar if not slightly better MPG. I think the thing to remember is with more power you tend to drive less efficently and why not!? The power under your right foot is addictive. I admit fully I race through the gears from lights. The most impressive part performance gain is the power in 2nd and 3rd gear, it will throw your head back. Don't even think about buying one of these just get your credit card out and do it already."
Bluespark Pro - BMW 535d Tuning Chip
Had the box over a year now and was a bit sceptical at first. But to this day I haven't had a issue yet. Drove a standard 535d a few days ago and felt like I was driving a barn compared to the performance mine has with the chip. Keep a up with low end supercar with all the grunt top end. Most importantly it hasn't caused any issues so more than happy
Bluespark Pro + Boost Control - BMW 325D Tuning Chip
In a word Shocking! What I mean is shockingly good low down power now with the Tech2 box fitted - and slight improvement in MPG. Feels a far more smoother car now as powerband kicks in much earlier improving performance and reducing gear changes - well pleased!
CR Tech 2 - BMW E39 525D Tuning Chip
It's early days yet so it's hard to tell if my MPG figure has gone up, but the difference in power and drivability is brilliant! The 525D is a pretty tourquey, reasonably quick old tractor in standard form but the tuning box has definitely given it some extra low down grunt. I can enterd a roundabout in 3rd gear, exit at around 1200rpm and the car pulls like a train without feeling like it's being driven hard. I would normally have to drop to 2nd gear if i'd wanted to 'make progress' from low revs before fitting the box. The car also seems to get up to speed with less fuss than before. It was already a decievingly quick car with it being so quiet and smooth but this has now been exaggerated. I was a bit worried I might end up leaving more black clouds behind me, but this hasn't happened either. Well impressed so far and I have the 'jumper' in it's stock position and just a small turn up from standard on the dial. I'll report back once I've covered some more miles amd had chance to check MPG. I've covered around 70 miles so far so will see how many more i get before having to fill up again.

I was wary because of price but service incl. delivery were excellent. I am considering upgrading and fitting this unit on Wife's Golf 2.0TDI as I was very pleased with improvements in smoothness,economy and slightly better performance. I would definitely recommend.
