Modified valve control system
Hi everyone:
I actually drive a 997.2 C4S and thinking about getting a TT or TTS.
After doing some research, I encountered this piece of info:
In the 911 Turbo S models, a modified valve control system and an adaptation of the engine management, combined with an increase in maximum boost pres- sure by around 0.2 bar, enable the power unit to produce 390 kW (530 hp) between 6,250 rpm and 6,750 rpm and generate a permanently high torque of
700 Nm between 2,100 rpm and 4,250 rpm to deliver even more power to the road.
I do part of my driving in the city so higher low end torque is attractive to me.
From your experience, does the modified valve control system really makes a difference in the low end torque?
TIA

Hi chris:
Thanks for the quick reply.
Is this lag also an issue with the TT? Can it be corrected with a tune?
I do have a lag with the C4S and its not pleasant.
