so the red is goin to give me more than 5 or 6 and whats the 9th injector setup.

 

The 9th injector setup is Dodge specific, it is used to overcome the lack of tunability of the stock pcm for larger injectors.

 

Duh, me bad. I'm a dealer for STS so I know that, but I didn't catch on silverado, duh?

I've been stricly the sts hemi dealer and only dealt with them so I guess I was just in hemi sts mode, LOL!

 

thats cool man i was starting to wonder what the hell that was. oh well LOL

 

There are two red springs -- one has a narrower diameter (which is the 5.6psi version) and the other is wider (which is ~10psi). If you look at the spring in relation to the waste gate cap and diaphragm, you can tell which spring you have (the larger one uses all the space the narrower one leaves a significant gap).

fyi, my 10psi spring is red

 

how big of a gap you talkin about

 

The red spring in mine is rated at .45 bar = 6.53 psi AFAIK but I would see 10 psi with it on the 6L.

L = 3.28"
D = 1.885"
Wire = 0.147"

Just be aware that you will need to check your boost level after the install to be sure of what you are getting. You should also check your fuel pressure to be sure that your fuel system is up to snuff. Definately look into getting boost and fuel pressure gauges.
