TPS--Don't worry bout it
Fuel Pressure--Are you using a FMU(Fuel Management Unit)? I'm assuming that you are.Fuel pressure,usually most people start around 40psi at idle,the FMU raises it as boost increases.
Timing--Timing should be at 10 degrees BTDC,thats what alotta manufacturer's suggest in their kits(including mine)
