It's not necessary with those mods to chip the ecu. The beauty of owning an eg though is that it comes with the beloved p28 ecu and is OBD-1. It's basically the best setup for tuning. So, unless you get some more mods in there (either Boost, or some more N/A goodies, etc..) you won't really be able to utilize the chip's potential.
