Ryan.. the only reason I believe the 1g is better is that you can use dsmap to tune the car.. and run things like mmcd. And before there was converted non eproms.. there were not many 2g ecus out there that could be tuned. Im not saying one will perform better. And as far as those few extra things a 2g can do.. well There just extras and I didnt need them with my 1g biuld. But after using all the tuning options now. dsmap.. link.. haltec.. megasquirt.. If I had to do it again.. I would put a 1g ecu with dsmap in a 2g piggybacking the stock ecu for emeissions. Mainly for ease as I believe It would perform just as good.
