6.2 L9H VVT Engine Tuner

[Jk07]

Can someone please recommend a best tuner who has tuned these VVT engines?

 

Also can the VVT be turned off for tunning purposes?

Cool.

 

I did send email to them but no reply yet. I think i will call Justin directly.

Be patient, he works by email. If you send multiple emails you go to the back of the line. He answers messages during the week as there are tuning events over the weekends

Why do you want to mess with variable valve timing??? Isn't it the AFM you want disabled so it's not in and out of V4 mode all the time? You seem a little confused. Maybe I am missing something.....

It does not have afm or dod. Its a 6.2 l9h engine with vvt which needs a custom tune after custom headers and exhaust and custom cai.

I guess I didn't notice that information in your original post..

Why are you wanting to make an attempt to "disable" the variable valve timing that can improve your engines performance?
