I have a 2008 Evo I bought 2 years ago from a dealership and a few months ago I had a boost leak so i took to a shop and found out it had a tune on it but its stock with only a catback. So I've tried passing smog 4 different times in 3 different shops and it has failed every time. Right when they hook up the computer they don't get any codes and they're clueless to why it doesn't. The last guy I took it to told me to take it to the dealership and fine out if theres a trick or something to pass. So I did and the dealership was clueless also until they found out it had a tune. They said that's probably the reason why it doesn't pass and they tried to do a reflash but his computer didn't let him. He told me to take it to a tuning shop to reflash it back to stock and I got quoted for $500!! I was wondering if there's some one that can help me out with the reflash.
