yes your goin to need it..... and i would just get the bigger injectors and get a enginemanagment like dsmlink or keydriver chip to compinsate for the larger injector

If you're going to go with dsm link or a keydiver chip, be sure you have a socketed ECU, if you don't, then you'll need to find one.

There are several places slowboy AND FFWD carry dsmlink and there are lots of web sites that sell afc-neos that you can use to control just your fuel. The dsmlink will offer you way more features and tuning capabilities you just need to do some research and see what will best suit your needs.

You need to research like I said on your other post. We cant spoon feed you all the answers. You dont want to swap injectors for stree and strip. You also said you have a 16g. You will not need anything over 650s for that. Also you SAFC cant control anything bigger.

Jay, I agree with what you said except for the "You will not need anything over 650s for that" part. Here's a link as to why one should go with the biggest injectors the piggy-back/EMS unit can handle. I understand he has the SAFC, but he should understand why settling for 650s/660s/680s is not a great idea.

ok thats good i appreciate the help i would like to keep the afc and i will get 650s in a few weeks

Agreed. Be sure to upgrade your fuel pump as well.
