310 vs 350 tunes

[Sequential6.4L]

Getting ready to put my rig up on the rollers again, difference is this time is my new RCD 59/75 turbos, I've read that the ******* 310 makes more peak power then the 350 but I'm wondering if there anything about the 350 tune that my new turbos can take advantage of compared to the 310, maybe more fuel? Just looking for the highest number I can I guess, was gonna try some custom gear head files as well but I've run outta time so ******* it will be.

Thought the issue with the 350 was to much pulse width. Stock fuel system couldn't keep up. I'd stick with the tried and true 310.

That's would make sense, my truck was barely touching 24k psi or rail pressure on the 350, I'm able to maintain the rails well above that with the 310
