Hey guys, i need some help. the predicament i am currently in is kind of stupid. I have an 03 evo8, that i put gsc cams in 272/264, 3 inch turbo back exhaust, no cat, perrin test pipe, walbro fuel pump, fidanza cam gears, stock air box and filter, and the VISHNU XEDE setup. i recently ran a 12.7 at the track, but i need to get an XEDE FLASH to the ecu to bring up my midrange boost levels and raise my rev limit. i sent in my ecu to shiv at vishnu and he said that he cant flash it because there was a dealer flash that was done on it for a p0300 random misfire issue. My question is how can i go back and revert the ecu back to before that dealer flash was done? i hate to buy a new ecu. i talked to a couple people and they say Al at dynoflash can do it. but for some reason i dont trust it. if shiv couldnt do it, why would he be able to. i need some direction. can the dealer set this ecu back? i dont see a flash like that being permanent.
