But a tuning box is an easy affordable solution for those of us who cant go the full remap

I had a tuning box in my mk3 leon cupra. Quoted figure was something like 350hp. I never put it on a dyno so I dont know what it actually made but it was noticeably quicker than stock. But it just felt off? The gearbox didnt feel seem to like it and i just got the sense the car was struggling. Switched to a custome tune and the difference when out on the road was huge. Drive so much better and obviously with a TCU tune the gearbox is alot smoother and lightning quick on the changes. Custom tune all day long for me👍

MAP custom ECU tune is the only way to go!

What do you recommend to tune my 2016 bmw x5 35d ?

Excellent video review. Spot on mate.

Superb video, thanks 👏🏻👏🏻👏🏻

Hi lads, very informative.

I have been watching the Box tuning videos and I figured that if can be tuned off pretty easily which can significantly save fuel by running the car in stock using the app to turn it off or buy removing the box.

How much is an custom Ecu tuning on ml420cdi with 35000 miles

you can get these tuning boxes very cheap sometimes, i bought one for my bmw 218d 150bhp with as standard it said it would take it up 189bhp. it cost me £70 quid of ebay ''tigertuners'' haha and just pluged into the railpressure sensor. soon as i put it on i felt the extra tourqe instantly :). paid for a dyno run found out my car was 148 standard and the tuning box took it to 176!! that will do for me :) nearly 30 hp for 70 quid hahah
