I would buy a different tune. Trifecta really messed up the tune imo. The mpg really dropped after I updated and the throttle response is terrible. Barely pressing the gas pedal causes the car to think you want 60% throttle. I ended up switching back to the old select-a-tune.

Hey Guys,

We have most definitely addressed the 'touchy throttle' issues that initially were a problem upon launching the new more powerful update. Everyone that we issued a revision to was happy with the updates. Those who's calibrations required more finessing let us know this, and we were happy to oblige.

We have noticed that the reality is, that most people (every 14 out of 15 customers) are happy with the calibration as it stands.

I have stated this in other threads and via PM's: if you are not happy please let us know and we will do everything possible to work it out




I noticed that you never got back to us after we issued you the second revision. I see you downloaded the file though. We were expecting more feedback from you to see if we needed to revise it again.

Thanks,
Michael

That's because the tune is still not right. The last two tunes I was sent make almost no power. Just to drive at 65 mph on the highway I have to drive at half throttle and in 5th gear. I ended up going back to stock just to save on gas. My mpg went back into the mid 40s just by switching tunes. I unfortunately don't have my original select-a-tune file anymore so now I'm stuck and not happy.

I just really think this new PAL tune system is far too aggressive to get good gas mileage out of it. The performance is fantastic but I'm not willing to give up 5-7 mpg to have a little more power. I think Trifecta needs to have a separate tune for people who like select-a-tune. I just want a tune that has a linear throttle response and that I can switch on and off like before. The throttle response on the new system is way too sensitive.

I installed another updated tune and it feels better with better mpg as long as its a flat road but I just can't stand the non linear throttle response. 25% throttle is causing the engine load to shoot to 80%. Just barely pressing the gas is the only way to drive normal. Anything past half throttle is really 100% engine load. I just don't understand why anyone would want a non linear throttle response.

I originally installed the tune to maintain my mpg and to add more power. The original select-a-tune did that and was great. The throttle response w's great and I had a choice to be in eco mode or full power. This new system doesn't do that anymore.
