Got my car tuned last week. Below is the dyno sheet - I have 257 WHP at 5200 rpm and around 366 NM. The torque curve is flat from around 3100 to 5100 rpm. The lower line is boost - it peaks at 1.16 bar but generally is around 1.1 bar and 1 bar is reached at 3000 rmp. From 5200 rpm it starts to drop until it reaches 0.8 bar at the rev limiter (you can get higher boost but due to the back-pressure it does not provide additional power. The car was on the dyno for 3 hours, thus at the end when final tune was done, it was quite hot. Above 5500 rpm there was issue with the signal from the reference sensors (or some other reason that caused bad signal), therefore there is power drop at the end. Will try to fix it later.
Details about the engine:
AFM delete - it has VEMS
OEM air filter box, OEM fuel pump (it still has big reserve)
Stock head andd block, except small windage ports in the block and Wossner rods + Teflon crank scraper.
Siemens DEKA 630 cc injectors (not the best choice for two reasons, unless its for track car - spray pattern is suited for 16 valve engines and the spray volume is not as linear as it should be which creates issues at idle)
3'' dowpipe and cat-less exhaust with two stright through flow Magnaflow resonators
APR head studs
Tial 38mm WG
Boost regulated through VEMS and MAC solenoid valve
rebuilt and balanced K26/6 turbo with Bulsseye cold side drop in wheel and slightly modified hot side (4 mm bigger wheel and housing).
The car feels quite fast compared to stock as well faster than with A-Tune
