So... Very enlightening day yesterday.
Again a huge thanks to Nick at R-Tech
http://www.r-techpower.co.uk/ for all his help.
Really highlighted the importance of getting your car tuned by a company with the tools and knowledge to fault find and properly diagnose the carSo I'm happy to eat humble pie and admit that it seems the map that Motech applied was pretty poor. Nick checked their software against a known DSG map and found an area of code that conflicted. In his words he had "seen it before and presumed it was an area in the engine map where DSG and Manual differed but this confirmed it for him". He applied the DSG code to the motech map and I went out for a test and the issue was 100% solved instantly. I can also confirm that all of the drive home and driving last night the DSG change is now quick and punchy and the power is straight there afterwards like there is no let up atall... or im lamans terms... How it flipping should have been after Motech mapped it.
In short.... Motech had uploaded a map to my DSG car with Manual coding in it and this was affecting the power after the gear change.
The fun continued when we put the car onto the dyno..... which came at a VERY VERY lucky time for me as just as my car was put indoors... this happened.......

Motechs stage 1 now adjusted for DSG ran 214bhp@4467 and 284.9@3247The worse thing was Nick showed me the N75 duty cycle was at 98% the whole run so the poor little turbo was working flat out to try to meet the levels Motech were requesting. He also said the fuelling was very heavy (hence my constantly black exhaust and dirty rear end)
Nick lept into action and checked the car over and ended up changing the PCV as it was showing signs of sticking intermittently. This got us to 225bhp but the turbo was still working flat out.
He checked and changed the DV as my 6 month old rev D DV had broken and was bleeding a bit of air.
He has advised I get a rev G now and said that everyone should listen to him that rev D are poorly designed :) Unfortunately a new DV didnt cure the power or turbo effort but at least I know its not going to fail in the near future now.
He then decided to completely remove the motech map and apply one of his own that he then spent a long time tweaking and customising in between various power runs. The end result was:
R-Techs Stage 1 custom ran 234.3bhp@5599 and 281.8@3131 The N75 duty cycle was also down to 85% in the middle of the run so much healthier for the car.
Nick has advised that I get the pre cat knocked out and then run the car for a month. Because of the motech over fuelling its likely that the cat is pretty bunged up at the moment but now the fuel levels are reduced this should burn off and allow it to breath better again. I'm also going to try to get an air intake to help with the flow as well and then return in a month for another few runs and hopefully with will then be a nice healthy stage1 with 240+
So all in all Nick spent about 6 hours fixing someone else's mess
I urge anyone looking at remapping their car that is close enough to use R-Tech. If thats not practical, use a tuner that has a dyno and knows what they are doing!!!
