As usual, they don't talk too much about the box, except than it is changing injection duration within the same timing

If you look at the top of the page you'll see that this is the UK section, not U.S.!

Or do you mean the DTUK does not increase fuelling or turbo boost?

The crude tuning box s withonly one or two connections like the DTUK increase fuel rail & boost pressures, which can cause problems. And they fool the cars ECU into thinking it's running at lower fuel & boost pressures than it is!

The Steinbauer, ACS & Hartge change the injection duration by pwm, which is the way the engine was originally designed to operate. Also they have far more connections, one to each injector & one to the exhaust temp sensor.

Also those boxes do not make the cars MPG guage innacurate, the DTUK etc ones do.

Kindly correct me if I am wrong.
Individual connection going to each injector means that tunning box is increasing more fuel and chances of your egr getting clogged will be more. I may be wrong on this though.

I think I need to sit and read the difference in different method of tuning. I cannot understand how does fuel and boost pressure increase the BHP and torque.

More fuel pressure means more fuel goes into the engine, more boost pressure means more air goes into the engine, both are achieved by the tuning box 'fooling' the cars ECU into thinking the pressures are lower than it really is, which in turn causes the ECU to increase the pressures. This puts extra strain on the turbo and fuel rail.

The ACS, SB & Hartge don't increase turbo boost pressure (although the turbo will get up to full pressure quicker, and have less lag) and they don't increase fuel injection pressure, instead they increase the duration that the injectors spray fuel into the cylinder, which is the same way the engines ECU would get more power from the engine.

I'm not saying you will get problems from the DTUK type boxes, but it is far more likely. If you search the web for problems with Steinbauer boxes you won't find any, i searched for days!!

Good to hear that. I checked DTUK and Steinbauer box. Both have TUV certification and I could not find negative reviews on DTUK boxes for beamers.

Also, I looked at the specs of both boxes. Output is same. I have also kept an eye on my exhaust to check if I get any black smoke, but none.

Will be keen to hear your feedback.

We won't get any black smoke on our cars as the particulate filter catches it all. The problem that all tuning boxes could cause is blocking the filter and killing it! You don't want to know how much they are to replace! I haven't heard of it happening though.

hello, looks like the power kit comes with a new torque converter for cars build from 7/13..
it could explain the higher price, add that and a couple extra hours of labour..
