OK, got the euro grill in, nicely cut up the portion where the air intake feeds from so that direct air is pouring in.
Opened up the airbox. Removed the resonator box, and the guard piece inside the airbox.
Cleaned out the K&N. New NGKs.
Set FSE to 3.0 bar.
And still throttle response seems abit slow. Takes awhile for the engine to respond to sudden throttle changes.
I'm definitely getting some ram air response from the new grill set-up and the car revs up easier now but I remember better throttle response even before these mods.
AFM's been changed not too long ago so what's holding it back you reckon?
