All pipes/intercooler pressure checked , correct heat range (7)and gapped plugs, reset ecu, Manifolds checked and tightneed, turbo removed and checked. Dynoed and mixtures seem solid at 11%(S-AFC installed and waiting for tweaking). When its warm(weather wise) it will pull through the rev range smoooth and hard in all gears, when its cold(weather wise), starts missing as it pulls higher boost even in second(high boost means 10psi in my case, no where near factory cut off). AND, fuel pressure tested under load OK and boost gauge tested as well?????? I tell ya it annoying but at least I know whats NOT wrong with the buggar!!!
