Trifecta GAS tune?
Hello,
I purchased the Trifecta tune and was sent 2 files. 1. for E47 and 1 for GAS or 93 octane. I tried the E47 tune first and was getting a good 26psi boost. Competitive mode button ON. I was very please with the tune as it was an improvement over the GMTU. Since there is only one gas station near me with E85 I deiced to try the GAS tune. After i burned off the E47 mix and filled the tank half full with 93 octane.Loaded the Trifecta GAS tune and I will not see any boosts over 15psi. But when I switch to the GMTU tune via the Competitive mode (OFF) button I get 22psi boost? In the same condition. I tried the cruz control button and no change. I reloaded the file 3 times. I did email Vince.. Whats your opinion? I see Trifecta isn't doing tunes for HHR SS Automatics anymore....... |
The computer has rules about calculating the mix. I imagine the Trifecta is the same sort of thing, maybe more involved.
