Popping Under acceleration

[Rawze]

To ensure it is not program related ...
Copy program from ecm and e-mail to to me for a review of what is in the ECU. For all anyone knows, it could be in need of software update, etc.

- Also, after backing up the ecu programming as is, re-flash it to latest factory software and run it around the block with the factory programming in it ans see if the issue clears up.

--------------------------------------
Mechanically, as far as the popping goes...

== If the overhead cam is not damaged / flaky and worn really REALLY badly then its not likely the cause.

== What wedge was used on the valve cam?. - You sure it was wedged right? and was not out 180-degrees?.


== It is all OEM turbo, manifolds, overhaul kit, head etc?.

== OEM injectors?.

== It it all matching components according to the engine ser#?


== What are the intake/exhaust valve clearances measuring at this point, now that is has a few miles of running on it?.

== Will it pass an injector leak test exactly as it shows in this video?..

== What is boost getting to in a hard pull // hard acceleration when its happening?.

... and .. what are you calling a popping?...

... a 'Chihht' ... 'Chihht' ... 'Chihht' ... sound?...

or a distinct, sharp ... "Pop" .. ... "Pop" .. ... "Pop" .. sound,?..

??? or something else?.

is it subtle?... or very loud?... etc?.

and is it every revolution of engine?.. every few revolutions on the r3egular/... or simply random?..
