I had the ZZP pulley system installed with a 3.25 pulley. After a scan while driving, I am getting 4-6 degrees of knock at 80% throttle. Obviously I need to do something. My current mods are:
3.25 pulley
Thrasher CAI
Intense 1.9's
Ceramic TOG's
DHP
MSD Wires
180 Thermo
Ubend
I am guessing that colder plugs are a must, but what else can I do to reduce knock? Should I see Charles to have my fuel mapping increased? The scan showed that I was running lean at certain points.
The car hauls ass like you wouldn't believe, but I am taking it easy until this issue is resolved. What level of knock is safe or acceptable, given these mods?
Any help is appreciated.
