Audi A6 C5 Allroad 2.7 BiTurbo 300+HP

I have owned the car since Oct 2021. IT HAS A VIBRATION AT 80km and above that needs attention! I have extensive service history and info if you message me, I can't fit everything here. -Electric Recaro leather seats, fronts heated (great condition) -19'' Audi LeMans OEM rims -Android Head unit with CD player -Sunroof Some of the main points of work that have been done: 1. Manual transmission conversion - 6-speed manual from 2.5TDI code FTL (changed gear oil) -Clutch Pack (wore out quickly) with Fly Wheel from Audi S4 B5 2.7 (Clutch and pressure plate was changed with new "Vemo' set later on in 2022) -Front driveshafts -Propshaft + added perfromance bearing carrier from JXB UK (400£) -Rear differential with changed oil -All the necessary peripherals (pedals, gear stick, etc.) *Flashed ECU professionaly to accustom manual transmission - new flash + air lift module settings for manual, etc.* *Custom remap for extra engine efficiency, power, economy - I have measured ≈320HP from MAF accounting for 20% losses. Factory is 250HP* *Propshaft needed balancing - done by Driveshaft Services Dublin (300€) 2. Refurbished and balanced K03 factory turbos (as seen in pictures) - great result and increase in performance. 3. Complete overhaul of engine bay - motor out for full service, including head gaskets, timing belts, water pump, vacuum lines, thermostat, leak preventions and many more ( I have a full google album with videos and pictures of the project). Engine bay has no oil whatsoever after that. 4. Complete overhaul of poorly installed LPG system: -Fast injectors LPG Tech Yeti x6 -Vaporizer KME GOLD GT (tested for 300BHP) -Full rerouting of el. harnesses and better relocation of LPG ECU -All supporting elements, consumables - brand new - hoses, fuel sensor, etc The LPG system has given me 0 issues ever since and has performeded immaculately. Consumption: 14-15l/100km on LPG (used to be 20+ with auto gearbox) and 12-14l/100km on Petrol Lots more info if you message me.
