Was just reading up on the Trifecta, looks like a flash program via PC. I went to their web site and it only lists 2.0.
If this is a tune file, why is it no longer provided... you'd think it'd just be a file to flash?
That's odd... Hmm?

Thanks for the info on the ZZP downpipes!

Reached out to Trifecta, they will provide a tune for the 2.2. In communicating with them, both ZZP and Trufecta now do a tune file with provided cable. Near identical procedure currently... I understand Trifecta used to have a little different procedure. Trifecta indicates they are the only one that also tunes the auto transmission... is this accurate to those that have ZZP or have tried both. In the end, it sounds like Trifecta provides a flash file as is, no tweaking were ZZP states they'll examine logs and continue to tune until they obtain optimal tune for vehicle.

What are you all using or recommend based on experience?

I'm not sure how many guys have tunes or are actively seeking/trying out different ones these days... It was more popular several years ago.


My trifecta tune involved data logging and fine tuning... also included the transmission. Can't see how a "canned tune" would do much good.
