AFC spring kit

[pwknapp]

Ok put the new AFC spring in and had to use the lightest one. Holy smokes Batman!! Star wheel fully forward, and its a puffin'. Turned back the wheel 2 turns and it helped some but romped on it in 3rd and the cars behind me and going the other way had to slow down because the sun was blocked out. Guess I'll have to put in the stiffer spring so I can still play in traffic without getting a DEQ citation. Anybody else tell me the best set up for low end fueling and much less smoke?

With a 215 hp, use the medium spring and around 10-20 clicks away from rich. Or, with 215 and the 370 injectors, even the stock spring may be needed if your foot is indiscrimately heavy and you are in a smog-alert area. If you can learn to lighten that right foot, the medium spring will work well.



Of course, my truck doesn't smoke

I've been checking out this kit and want to get one

but I'm not clear about the benefit. Could you clue

me in? Thanks!

More fuel in the low end... and better throttle response. Lighter springs allow the AFC to respond better to boost and increase fueling.



The AFC springs are easy to change, and the kit is priced right.
