Hi I'm Wayne

I will help you with this

do you get a check engine light on

does it do it all the Time, on straight road or take off

let me know Please

Customer: replied 1 year ago.
Hi Wayne, sorry on the response but truck went out and didn't get back till now. No check engine light but throws an inactive code for turbo, but has a new turbo on it, doing the same with old turbo. Today threw a code for vgt calibration but again was inactive. It does not do it all the time, can get it to do it when sitting with foot or cruise at around 1000 rpm or even 1700 rpm. When driving on road it bucks and sometimes real bad. Still no engine light. This has been doing this since factory, OEM replaced 12 injectors, tested throttle control body, EGR valve, replaced full exhaust system. We tested all the wires going from MCM to VGT with a lamp and it powers up lamp, checked all cables, powers and grounds, went through majority of wiring, we checked parameters(good), program seems to be ok can't see nothing out of the ordinary. Look forward to hearing from you

Everything checked good , and you checked all possible cause

The only thing left in my opinion

is a glitch in the ECM
