I own a 2011 Audi a4 211 bhp 2.0 tfsi quattro saloon manual and i am going for a stage 1 revo remap soon,
The revo remap will go from 211 bhp and 258 lbs/ft to 305 bhp and 320 lbs/ft which is a stage 1.
Then engine factory standard on the 2.0 tfsi b8 has a larger turbo and a excellent intercooler and a vvl engine (variable valve lift) which is very responsive to tuning and can withstand the power of the revo remap without no other modification or upgrade safely. the power is still within its limits other of other engine components not to get damaged, revo told me that they would not put my car under any harm because if something went wrong there would be a bad name for reco.
As the car has a tri core locked ECU to prevent remapping. they will take the ECU out of the car, the ECU is bolted in by bolts which the heads pop off when they are fully screwed in so they have to pattern a screwdriver pattern on the bolts locking the ecu in and unscrew and unlock the ECU via there computer and insert it back into the car again, and put new bolts back into it again so Audi can not tell that it has been fiddled with rarely they look at the ECU anyway. then they remap it by the old fashioned way ( under the steering wheel)
Cant wait to get it done
