Feels like it’s missing when you got to take off or get back in the Throttle  kinda feels like it’s sugering but after it’s gets to a certain point it runs fine like nothings wrong  I’m runing the quadzilla adrenaline  for tuneing  is it possible that the quadzilla is maken it surge  when you take off or get back in to throttle   Truck runs fine other then that little problem 

Does it do it on lvl 0 ?  

 

have you scanned for codes?

 

whats your fuel pressure at idle and Wot? 

 

The truck Hasn’t thrown any codes or check Engine light will check it anyways latter when I get off  and at WOT I would say no lower than 14 psi thats what the data log showed it was  at idle it’s 17/18 psi. And I haven’t tried it on 0 o will soon as I get off 

Timbo apps, Ac noise, wt mod, injectors pop pressure, few things I can think of...

I ran it on 3 as normal and then 2 and then 0 it’s  a daily tune  it didn’t really do it I’m thinking it might be the Throttle position sensor only really does it first thing in the morning when it’s cold  I’m still learning everything about diesel  and it’s had the grid heater has been deleted  so could that have something to do with it  woth everything been cold intake air etc
