I've got full 4" stainless steel exhaust from the turbo back. I'm also going to put the heatshield and a BHAF in when I do the 4000 GSK with valve springs,191 DVs and AFC spring this weekend. Which AFC spring do you think I should put in? Thanks for all your help with my posts,Your making this alot easier.

I have never changed the afc spring always slide the afc housing and adjusted the star wheel can't help you much on the afc spring. Looks like you are off to a good start with the parts you have. I would like to know about the 370's and the HTB2 thats what I am looking towards as well.

I'm going to try to dyno the truck after I do the GSK,DVs and AFC spring, it should be the 4th of DEC then around I'm going to get some 370s, put them on and the HTB2 in my garage will be put on the same day. I will let everyone know the HP+TQ numbers of the 1st BOMB then after the 2nd BOMB

In my experence skip the AFC spring, all you'll get out of is hours trying to get it adjusted right. I've always ended up putting the stock spring back in.

Isn't it suppose to give it a little more throttle responce? The weaker spring will let it fuel up quicker, right? What problems did you have with the spring?

THANKS CRIS

 

Use the light spring.

 

Either low power or too much smoke. The lighter spring TST sells is longer than the stock spring so it ends up being stronger in the end. Perhaps cutting a few loops off the light TST spring would give better results.
