Need NOS Help

[My84Z]

With u not knowing if there is a hypertech tune ir something in there u r proba ly better off not. However definatly do a wet shot since a dry would be shot before the maf and u would need tuning. You can run a 150 safely on it lt1's love nitrous. Just get some colder plugs like ngk tr6's and run a small gap like .038 i wouls also run it for the first time on the dyno and run a window switch. Might also wanna look at an antibalooning tourque converter
