Perhaps it's these sort of engineering differences that restrict the maximum safe levels of tune.
How much different is the torque figure claimed by SCs? |
turbos, injectors and software are also different between the low (90-110) and high (130 -150)
superchips show
VAG 1.9 PD 130 as 167bhp and 386Nm (285 ftlb)
VAG 1.9 PD 150 as 185 bhp and 357Nm (263 ftlb)
