hey everyone, new here but not a newb, just another car,lol....so i picked up this 94 z28 and ive had it about a week and i noticed a tag on the door so i removed the ecu and found the piggy back module. ive searched there sight but found nothing. is this just like some 300 dollar promise of 30 free hp? lol? whats the deal here? the car does feel pretty fast . i dunno. i cant scan the ecu eithier. ive tried with 2 differant scanners. wondering if this is because of the chip? and yes i did search. all i found was a question about installing one and the red wire:) thanks in advance guys
