PCM Diagnostics & Tuning - NA motor mail order tune vs nitrous mail order tune

so im runnin a 150 shot, along with all free mods, LT, true duals, 4.10 gears, etc etc. so i was looking at sending my ecu into get it tuned and was wondering if there would be a benefit to get it tuned for nitrous? would it hurt performance when i run it on the street on NA? could it be switched from all motor tune to a nitrous tune? or it doesnt work like that. i dont think you could switch it, i was just curious.

A nitrous tune for a 150 shot should have some timing pulled out compared to a n/a tune. Also depending on if your a wet ot dry shot you may need to alter the a/f ratio by adding fuel or pulling fuel if it was a dry kit. Now for a wet kit you could adjust the fuel by jet size or with the pcm and injectors.

im running a wet kit. so im guessin a wideband A/F ratio gauge is a needed part? would you just tune it for NA? or nitrous if you were in this situation? or contact Frost and see what he says?
