Thanks again. Got another question - do you think the 8.1 truck injectors will be enough fuel? I've got some 12613411 injectors that came with my nnbs intake. Would these be better? Also is tuning going to be any easier with one or the other? I've also got a walbro 255 pump going in the tank when this goes down. Thanks in advance.

Using a rough guess here with a few online calculators, 31lb/hr injectors should be okay for 500hp at the crank give or take some. So with a conservative tune they should be just fine.
The 8.1 injectors would be drag and drop for injector data because the data can be pulled straight from a 8.1 file. The NNBS injectors would take a little excel work because I think some of the values are different with the newer computers.
