Bit of thread necro - apologies have not been online for a while.
I wish I was able to attend the dyno day last year with Mark - would have been great to have a baseline figure before doing any further mod/tune. Life and work have been in the way.
Previous mod: DV+, downpipe, TDI box, custom skirt/diffuser
New mod: Snabb intake pipe, do88 FMIC
No figures/data beyond butt dyno. Compared to stock - air intake sound is noticeable, diverter valve sounds like a bov, downpipe soundtrack is throaty and addictive. Yet the car is silent and civilised when not in sports mode.
Performance wise - throttle response is faster and more top end compared to stock. Without a dyno sheet its all subjective.
