I am having a Vortech SC installed in the next week and was wondering what the ideal A/F ratio should be. I just want make sure I know what to look for when I have it tuned. So far the only other mods I have are Top Speed headers, test pipes, y-pipe, 3 inch pipe (no cats), and Greddy SP2. With that in mind what should my A/F ratio be?

How about if I add a APS or Crawford plenum to the mods?

Thanks

 

No matter what other mods you have . The Vortech out of the box tune will be on the rich side . When and if you get it tuned...shoot for a 11.5 to 1 A/F after 4,000rpm to redline

 

Thanks Booger. What's the best way to tune the kit? I was thinking about the R4 software but I called two local shops and they told me they never heard of the R4. One shop said I needed the e-manage to tune.

WTF! I don't want to spend another $450. How did you tune yours?

 

Get the R4 software from Split Second. You might send a "PM" to: coletta z He is in Florida and used a tuner named Sam to tune his Vortech using R4 software. I also think: CaneZMD has the R4 software and also lives in Florida.

 

yeah, get someone that is familiar with the R4 software... it will be much easier that way, so talk to those guys recommended above.

 

I have many programs for the r4, and can get you very close. If you have a lab top it will take 10-15 min and you done. pm me
