Not always, it all depends on how close to the edge the tuner wants to go. I've seen a lot of bad tunes done with HPTuners if the guy doesn't know what he's doing. And I've actually had a few customers dump their Trifecta tune to get an HPT tune only to come back a few months later saying the car wasn't running right or broke something.

Trifecta has tuned literally thousands of LNF cars. But yes Trifecta does run a little conservatively.

 

I see a lot people saying that Trifecta is giving them 27psi. This is not conservative being that the efficiency range of the stock turbo is 15-25psi. I hope to compare notes in person sometime with someone that has the Trifecta tune. Anyway, it is only a valid comparison if you have someone good at HPTuners tune your car as opposed to Vince using his software to tune it. Is true that if you do not know what you are doing with HPTuners, you'll get unsatisfying results.

 

I will be getting mine dyno-ed soon I have an 09 auto SS with a Trifecta tune, I will post my numbers here but I am pretty sure I am around 24 to 25 psi...

 

If you ask for it they will do it, but typically if you just tell them to make the most power they will run 22-23 with a lot of timing. If you really care that much about running high boost they will give it to you and back off the timing

 

they should have went to a more competent tuner .

 

Well the excitement of the tune is worn off, I have a permanet " power steering " mwessage on the DIC, car idles way too high, auto start not working, stalls, bogs,really undraiveable, Mike of rawamericiampower tringg to figure out. No resolve yet, has anybody ever heard of this after a tune install.
It is like factory tune is gone.

 

Did you reinstall you stock tune with the same problem?

 

Same problem, tried to reinstall from the trifecta program.

 

Still no resolve, second tune keeps sayin cable unpluged, not , tune does not finish. Car runs like **** errors traction, esc, stab, ect ect.

 

Sorry to say but it sounds like your PCM is bad.
