Truck went to dealership for recall.. They reflashed computer.. Truck ran like any untuned truck would.. Couple days later it started acting up... Reader said multiple misfires detected.. Changed plugs and cables.. Reader said same thing.. Not sure if one of my coils is going out or truck needs tune again.. Mods in signature

 

You have no mods listed at this time.

Why was ECU reflashed back to stock at dealer???

 

Tr220 cam, lt headers, 3.73, intake, exhaust... Vette servo.. And that is a very good question.. I'm trying to find the papers on what the recall was about
