What's your actual AFR right now?
With your mods, I think you'd be better off a bit richer than low 13s. You've got some pretty decent cylinder pressure there, 12.5 would probably be a safer N/A AFR and make the same, if not better power.
At any rate, you'll definitely need more injector. Those marine 8.1Ls are sold by radix guys quite a bit, usually for $250 or less (mine sold for $200 a while back).

on nitrous it went over 17:1
the AFR map followed the Tq curve almost exactly. Its getting put on a wideband this week so we can get to work on it. I NEED me a set of those marine injectors. Are the pigtails and all good to go?? no splicing? same height as the stockers???

on motor it went to 10:1 almost exactly... 9.9 in a couple spots.

Thats what I dont understand.... its a 150 WET shot... :headscratch: I checked my jets and everything... the pump is definitely capable of handling it, I havent put a gague on it to check pressure though, thats the next step. happening today.

Ya that makes sense. I was thinking 5.3L with just bolt ons will be fine although pushing the top end of the injectors at ~87%. So with a 6.0L and bolt ons should use more.
