So I scored a SCT X4 (used/$200). Now I want the Steeda Bullitt tune

From the people that have done this mod did you go directly to Tuning by James or through Steeda? Has the tune diminished the crackle or is it retained? If I get the E85 tune will it always require E85 or can it be switched back and forth? If I get the E85 will I also get the 93 octane tune as well?

I did get confirmation the device has been unlocked/un-married. He sent me pics with date stamp and a specific hand gesture. I asked him to give me the hang loose...haha

Thanks for any insights!

A straight E85 tune will require E85 only. If you want the option to run E85, 93 octane or any combination of the two, you will need a Flex tune. That‘s the tune I run in my Bullitt the majority of the time. I have an nGauge which I bought through Steeda, along with the tune from Lund Racing.
