JWT Reprogram Options?

JWT Reprogram Options?
I have a JWT ECU coming that is set up for 550 injectors, 100 octane, and Z32 MAF. I have a stock MAF and 370 injectors. What program options should I ask for when I send it back?
Current Set up:
V1 blower with 3.125 pulley
Vortech FMU with stock disc
370 injectors
Stock MAF
Walboro 255
With the JWT I am going to get rid of the FMU and probably add a FPR.

Neal - 18 degrees max advance.
That is probably my old ecu if you bought it from 95stillenmax. It has a 7000rpm redline, and the 550cc injectors are at 3.5 bar fuel pressure, this ecu was setup specifically at 3.5 bar fuel pressure for use with a VQ35. The injectors do not flow 550cc at 3.0 bar fuel pressure. Other than the Z32 MAF, it might run really well on your car cause it was lean with mine. I had to add a bunch of fuel with the SAFC. Do you have a wideband and SAFC or some other tuning device?

That's pretty low advance. I'm wracking my memory trying to remember if all JWT reprograms made poor power because of too little advance, or if that was a problem with the 550 and Z32 maf reprogrammed ecus only.
