6.2 L9H VVT Engine Tuner


Recommended Posts

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

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?
