Trifecta tune

I am considering a Trifecta tune, I have a 09 HHR SS, with a ZZP 400 cell cat, installed, I also have a stage 1 (3 bar sensors - not installed).

I am thinking of going with the tune and not the selecta-tune option, as I am told that the 3 bar sensors will not work with the stock tune, and thus the selecta tune would than be an issue.

Trifecta say that I do not need the sensors. but I have them, and was told that the higher boosts would benefit with them. and I would think that Trifecta should be able to get more boost in the tune with them also,

looking for input on whether I use the 3 bar sensors or not, and whether a trifecta tune or a custom tune would be better?

Trifecta will know what works with their tune.
I'd follow their instructions.

You can also get a hold of ZZP and have them do the tune for you ...but if you can find someone who can tune via HPT instead, it is better

I have the selectable tune from Trifecta and do not have the 3 bar sensors. My analog boost gauge shows peak boost at 24-25 before settling to about 23lbs.

+1 for ZZP, trifecta's customer service was terrible for me.
