man my truck sounds really bad spits and spudders when i rev it up its fine i am thinking bad gas so i replaced the fuel filter and got some octane booster but i noticed it only does it when the charger kicks in otherwise its fine what do ya'll think

 

is it stock or modded?
If modded, the chip may be loose?

sounds like bad gas though..

What else has it been doing?

 

it has a 2 lb upper pully thats it and it just start yesterday but thats all it does it spit and spudder bad shakes the whole truck when it does it

 

Sounds like a chip issue...

Although what does it drive like?

Does it still pull hard when you give it throttle?

What mods have you done (again)?

what were you driving like last when you shut it down?

And how old is that gas anyway!!!
