I am wrapping up the last bit of assembly on my 6.0 LQ4 marine build. This is the 4th LS i have dropped into a boat and let me say, all 3 of the others were incredible. ANYWAY, heres what i want to know:
Is it possible to nail down a decent tune without a wideband OR front o2s? the reason i say this is; a typical marine exhaust system is wet. the last swap i did i tried to put front o2s in and they almost instantly fried from the water. I had them in the dry side but you still get steam/ moisture as far in as the exhaust ports in the head. I wiped my wideband the same day trying to use it instead.
I still have the option of running the MAF and MAP as they are still installed. if it is possible to do this how would i go about it? i have never tried tuning without using the front o2s.

Thank you!
