Yup. I switched back. I'm sure going to miss the extra pep, but my Cruze was having too many problems with the tune. Vince tried explaining that it was normal, but I'm sorry, I'm no dummy.
I originally had the occaisional P2097 - Post Catalyst Fuel Trim Over Limit. Vince sent me a 'fix tune' to take care of the code. Said it was nothing to worry about, and he's had 7 years of tuning experience to back it up. My response is, 'Why is no one else setting this code then?' It would happen on light cruising after some harder accelerations. I didn't think much of it.
Now, my check engine light came on today. After checking the codes via EZFlash, I now have not only the P2097, but 6 other codes. Fuel trim codes, Barometric codes, IAT codes, and Pressure codes. The turbo is functioning properly, I've already look into it. The turbo was my first guess.
I took the tune off and cleared the codes. I'm going to provide proof of the question everyone seems to have with the tune. 'Is fuel economy really better with the tune?'
My answer after driving 20 miles after reverting to stock tune, 'It's not looking good for Trifecta." I was able to maintain a 57mpg at 10inHg of vacuum while cruising in 4th (manual trans), which even with the 'Eco-tune' at the same vacuum, I only saw 38mpg. I'm going to test the mpg on stock tune tomorrow on my commute to work. I was able to achieve a best of 43.5mpg via tune, I'm going to see if I can beat it. I will post results.
