OK folks I am fed up with reading how well some S3s go with a tuning box and might actually get round to trying one (just out of curiosity). Looking on various forums the DTUK seems the most common in the UK whereas the JB1 seems most common in US (particularly on VWs). My original plan was/is MTM (after reading the excellent write up between DTUK & MTM) but interested in an intermediate step just to play with first and given the feedback from the US VW forums defo seems like a sensible step.
My understanding (which may be wrong of course) is that the JB1 is currently the only one that attempts to look at air/fuel ratio which will be critical for long term owners of both the car and box, is that correct? I know people on here have bought both and I am curious as to whether they still use them and how many miles they have done whilst using them - I have a manual S3 so again want to hear of any clutch issues etc specific to the manual. I am not actually interested in peak power nor 0-60 times more just making the current power delivery stronger, car still has a couple of years warranty which I am reasonably keen on keeping but am already aware of flags/risks etc etc
From those VW forums which are in the UK and US they seem to rave about the JB1 and in fact I struggled to find anybody with a negative comment, probably more so then DTUK but I got the impression that the JB1 is slightly more advanced in its electrickery and logging of information in the ECU which Audi could interrogate if they got interested. JB1 seem to have a massive following in the US for their BMW tuning so should absolutely know what they are doing.
p.s. if this has all been done already then sorry to waste your time and please delete this but please point me to it as I have already looked!
