I don't know cause I took off my cat and all these problems started right after I thought it was the edge w/juice so I removed that and got the codes again. I took it to a diesel shop and he said my egr is probably shot but never mentioned anything about boost leak he said the one problem is making all my codes and I did put a new air raid intake on could that have cause my map to get dirty maybe?
LOL, nope not me. The 0299 is what's causing power loss. You might need to rescale your maf or you might have a boost leak (doubt it though). This shit is very common after exhaust and intake on the LLY. EFI Live can take care of it all though. Rob @ ATP can hook you up.
