Morning,can anyone tell me what there timing is from 6000-8000 on row
18&19 boost rows please as my car is trying to trying to detonate in
this range.Ive tried lowering timing and adding fuel but doesn't
help,most of the time it is fine then all of a sudden it starts to
play up and it hesitates badly so i back off quick and the knock hits
90 or so.Any help would be great,The only thing i can think of is the
cosmo 20b pump that i fitted recently cant keep up with 1 bar boost
but it also does it at 3/4 throttle.Thanks.
Mods are intake,dp,mp,blitz catback,front mount,mild port,cosmo pump with standard wiring to it.
