so the fc that i picked up about a month ago is bogging down hard on acceleration when i try to go full throttle. i keep hearing that this is a very common thing but having gotten any feedback on how to help solve it.
any help is much appreciated.

bogs down around 3000-38000 rpm to be more precise.

 

s4 or s5?
have you tried setting your TPS?.(tons of threads on that).

 

um im honestly not sure. its na. but no i havnt tried the tps, i started this to simply find out if that could be the main cause.

 

Search grounding issues related to 3800 rpm hesitation.

 

Clean up the three ground wires, that's where I would start. Most likely cause from what I've read

 

Stay above 3800
