ecu chip

[montess408]

i have a 88z24 and i just got done refreshing a 3.1 for it nothing to wild mostly stock stuff with a mild cam and a 65mm T.B and ported uim headers udp and a nos kit so my question is would a off the shelf chip work or would i have to with a costum one ?
and i am thinking on building a 3.1/3400 hybrid later on so will the chip i get for on motor work on the next one ?
