Hello all. I just bought an 04 Optima, and I love it! I've seen alot of ads for power chips to boost performance, but it seems that they are all just 50 cent resistors that kill your gas mileage and add no noticable performance boost.
Are there any true performance chips designed specifically for the 04 Optima?
