I am worried about the long term effects on tuning emission compliant cars. I dont think the current DPF/DEF system can even handle the stock tune. Fleece warns of additional DPF regenerations with the tunes. Time will tell. Its just my opinion. Send me a PM if you ever find any "off the grid" modifications. the people who have it seem happy with it.
Well I've seen where duramax has a tuner for the cruze now and I was unsure which would be better. I haven't tuned a diesel but I want to improve my car's performance without destroying it lol.
