Just wondering with the supporting mods in my sig what kind of gains I can expect with the 1x installed. Or anything else I need to know before this gets installed. Anything else besides the springs?

i would recommend either oil restrictive lifters or pushrods along with the springs and upgrade to the stage1 pcm

i went from 1.9 rockers to stock rockers with S1X cam and gained 3-4 tenths on my 1/4 mile ets.

i would expect similar results from your set up.. 4-5 tenths
every car reacts differently to mods though so its very hard to tell
(my car hates me... i dont get nearly the gains others have had with my mods)

S1X is an awesome cam grind and you've definitely got some nice mods to go along with it.

I have the XP...let me know if you ever want to check it out before buying something. I doubt you could tell the difference between a S1X and XP car by listening.

With the XP the modded retainers are recommended...

I wanted to use titanium retainers, so I switched to the PRJ Viton Valve seals which give you the necessary clearance...just a little more moolah compared to the modded steel retainers.

Yeah! I would definitely like to check it out. I was going to just get the rockers, but I think I changed my mind.. Too many decisions!
