Yes that set up will work fine, but why not get bigger injectors... Get the 850s at least
why hold your self back since you have a means to control them all the same...

I agree about the logger, and a wideband should be thrown in with that list as well.

If you want to change later the $20.00 charge for a reburn is cheap , even for DSM'ers.

I run the n/t fpr at 48 base psi, it lowers fp over run a good amount and makes your injectors flow like there bigger. But i wouldnt run this fpr if you plan to run beyond 25psi because fuel pressure relief valve will kick in at that point.

Just be specific on telling him your goals w/ the car and what parts you have in the mix.
He does compensate for inj dead time and global and all that, you can go on dsmlink boards and find out what your deadtime and global % should be for your injectors/fuel pressure and ask him what he had in mind and compare and see if thats the amount of deadtime you want. Or if you dont feel like looking i believe the global formula is
450 / (inj size you run) / 1.2864 - 1.0 = _________ - 1.0 = ( This would be your global %)
Mines is at like 315 us inj dead time w/ 41% global, i burn my own chips so im going to lower my dead time to 310us on my 850s... Wont change much but generally the higher the deadtime number the richer the burn, the lower the leaner.
