I have a problem deciding whether to choose between getting a tune or a piggyback. I seen a lot of posts about this and I know its getting old ha ha. But I got 98LS with 96 gsr b18c with a P72 OBDII ecu and I have chipped OBDI P72 ecu from phearable.com. I just want to be able to run optimium performance with what I got done to it for now. The biggest issue in deciding is throwing codes because I live in NY and Emissions on the inspection suck balls. I was thinking of buying the Venom 400 piggyback system ???
