ecm performance tune on stock mc 3.8
I have a stock 2000 monte carlo ss and I was woundering if it would be worth buying a performance tuned ecm off the internet, does the retuned ecm make a huge difference that's noticeable for the money its worth? or should I just keep saving. So for someone who got this done to there car please let me know what you think.
thanks
thanks
