Hi all Picked up my A7 BiTDI 2013 last weekend - lovely car to drive. Really enjoying it at present but I know having come from a Jaguar XFR and highly modified Subaru Sti that I will tweak the performance.......either sooner or later . I'm pretty well versed on performance upgrades on other makes (as above) and fully re-built my Subaru and re-forged the engine but keen to pick the brain of those with Audi diesel tweaks to date, as any info will fully assist me in my project/journey on the A7 as plan on keeping for a few years. With this in mind I've been having a look through various threads with folk talking about upgrades and each with totally different figures achieved, some doing the exact same things but having totally different claims of success. I initially thought a Revo remap would allow me to achieve a nice road car around 400bhp but having reviewed their figures I believe it would be around 355. I also contacted a local garage who I think hold an excellent reputation (EcoTune in Glasgow) and had a great conversation with one of their staff today and he advises the recommended Stage 1 (only one they offer) would see 350. So I suppose my 2 questions initially are - For an A7 BiTDI 2013 - is 350/360 the best results currently available? I asked about upgrading the Intercooler, filter etc....and was advised this would allow minimal power increase but certainly help the cool air flow. IF 350/360 is the actual plan now - is going to Revo or EcoTune my best option as I see some plug & play boxes claim almost these figures so are these boxes any good to use instead of Revo/EcoTune and if so can anyone recommend the best one to go for? Thanks for any advice as keen to get folks input who have already gone down this path instead of me starting off in a journey, then wishing I had went a totally different direction.
