I'm having my car's MoTeC M600 remapped by Dan Turner next week because I'm not 100% happy with how it idles when hot and the off-boost AFRs. (Car spec here)
Now, there's a few things I'm wondering about;
The fuel pressure is currently set quite high, about 50psi at tickover if I remember right. Should I get this reset to stock pressure before the remapping? I can't see why the 800cc injectors would need raised fuel pressure, or is it because I'm still using the stock fuel rail?
The exhaust cam (HKS 264) is currently advanced four degrees.

This seems excessive, I believe the stock cam timing is best, right? So I should reset it before having the mapping done?
Spark plugs. Does it matter for the mapping whether I the use NGK coppers (BCPR7ES) that are in there at the moment or should I fit the Denso Iridium IK24s I intend to use in future?
Thanks.
