Does anybody have any specs on These cams I'm trying to figure out why my motor is running funny an why my tune is for a Vs cam but a have a s1x cam anybody can help me

 

These are the specs directly off their websites:

S1X - duration 210/221 (@ .050"), lobe lifts .321/.329, LSA 115
VS - duration 206/216 (@ .050"), lobe lifts .320/.317, LSA 115
XP - duration 212/224 (@ .050"),lobe lifts .325/.335, LSA 116


Maybe you chunked a piston when you put the 2.8" on since your tune is off? What kind of symptoms are you seeing?

What do you mean that your tune is for a VS cam? How do you know the tune is for the wrong cam? I know in the other thread you said you had a ZZP tune- does that mean you bought a canned tune instead of a custom dyno tune?

IMO on a cammed, IC, 2.8" setup- you're deep enough in that you should certainly be considering getting your own tuning software, or taking it to a place that does PCM tuning to get a custom tune.

 

Yes sounds crazy but my tune says on the info print out on the back of my PCM it says xp cam an when my car is idling is shakes really bad it's not like a vaccum shake it's like more of a off balance shake it weird took it to a local performance shop an they told me it with out me even telling them it was cammed that something in that area might be off I'm not getting any codes or anything just a unnormal idle an with the xp setting being if there for xp an I have a s1x will that throw it off an all I have is Zzp to use there isn't any local shops that deal with L67 performance where I'm at

 

Ok so I talk to the company who did my tune an they said that a xp cam settings would work fine with a s1x anybody ever heard of That before?

 

i agree with bumpin, you cant expect a canned tune to work well with a car modded this far. you need a custom tune period. i also would check compression on all cylinders so be sure you didnt chip a piston as already mentioned...

 

I'm confused. Your original post says that your PCM is tuned for a VS cam even though you have an s1x cam. But then you say that your tune is for an XP cam. What's going on there?

 

Piston are fine I check them out already when Headgaskets where changed an I made a mistake but it's tuned for a xp cam an I have a s1x cam an it's hard for me to get a custom tune because no one in my area does anything with 3800 so idk what to do

 

Whereabouts do you live? There might be a member on here who can help you out with getting a good tune.
