Does anyone ever get bang on the quotes from the tuners?
I know that every rolling road will read slightly or sometimes very, different and every engine spec will be different.
today i had my zafira gsi on the rollers running ipf stage 1 high torque map which should be 237bhp and 274lbft torque.
it made 223.4bhp and 282lbft. the afr is spot on and the car feels great to drive but i'm slighty dissapointed the power wasn't a bit higher but i'm overall happy.
my full spec is veccy c pipe, airbox mods, panel filter, turbo back exhaust inc sport cat and hard boost pipe.
