I have a 7mgte mklll and I replaced head gasket and put a gt45 Turbo in it with after market header and wastegate. I just did the timing which it idles fine around 1000 rpm. But it seems like it's choking for gas trying to start it takes a long time to start up. But once started idles fine. Another thing is when idling when you apply the gas it instantly bogs and has no acceleration. I did see that my hose for the waste gate from the cold side of Turbo was burned in half and not hooked up but I will do that just a matter of time. Would that have that big of an impact on it? Another thing is I have a Maft pro setup in it and I reset it to default I figured this has to have a big impact on the problem cause my wide band is reading 22.5 at idle. It proly needs a tune real bad but any advise would be greatly appreciated.
