Need help, what tune should I use?

[bblanco]

Hello,

I have owned Flashpro for 2 1/2 years and have been using stock tune cal.

I just purchased Injen cold air intake and a 70mm test pipe, will be using stock header and stock exhaust on my 2006 s2000.

Now my question is what tune to use? Injen intake tune or Toda tune?

Another option is Injen tune with Toda Vtec set point at 4100.

Thank you.
