Hi all, well got my car back from the mechanic last night, new egr in place. My Navara is behaving as normal, no more acceleration problems, turbo works as normal. And no black smoke. Thanks for all the advice from everyone it was all very helpful. If anyone is in Brisbane and needs a turbo, over the weekebd I have a new one from ebay (I bought it just incase) I paid $280 for it. I'll sell it for $250. If no one wants it I'll send it back for a refund it will cost me around $30 to send it back. Thanks again
