Of course it will.. if ur able to do it, u should tune each time u get a different mod thats the ideal idea.. however most people can't and if u notice a different in power as you've done your b20vtec and have added these mods i promise u, it will be a night and day difference..btw keep your fuel pressure regulator stock settings.. dont adjust it its the worst move every you could do..Tuning with hondata would be ideal as well, i use crome on my car and have made great power...just tune the way you've learned from this fourm and keep us updated, it'd be wise to get a obd- 0 to obd-I conversion harrness cause you can only use turboedit(a tuning program) on obd0 cars its just like crome but not as good.. i'd suggest getting a conversion harness for obd-I and go from there.
