what does it do when u take the afc spring out?

 

it lets it get alot more fuel at low boost. so it will smoke a decent bit

i noticed it gives you alot more bottom end (off an idle or if you lug it) it doesnt seem to pull quite as hard in the mid range and i think it gives you a little more top end. not sure if it makes a power difference, but you can feel a difference.

 

Alright cant hurt try it for awhile.thanks

 

i have not had mine in since i bought my truck. i didnt notice much difference though

 

well tried it didnt like so i put it back in. hiboy u where right about it felt like it lost mid power.

 

Just to make sure. The afc spring is the spring under the fuel pin diaphragm correct?

 

yeah i didnt notice any difference when i took mine out its sittin in the glove box with the plastic washer and my tps and 901 yes it is the spring under the diaphragm that were talking about
