Haltech vs jwt eprom vs nistune

[DTRUONG9]

hi im new to the forum and need some help on tuning components. im about to rebuild my z32 tt and wanted to know if anyone has anything to say about the Haltech ems. is it really better, safer, and then jwt new eprom. or is nistune the way to go. i currently have the jwt ecu but i heard is not fully safe because its not custom. is paying $600 for nistune gonna be beter or even $1600 for haltech even worth it. I dont track my 300zx just a weekend sports car.

my current set stage: 3 long block, hks gt22530s, single pop charger, 555cc injectors, greddy evo catback, jwt ecu

adding: 740cc injector, dual pop, 3inch dps and test pipes
