I am putting a new cat back exhaust on, new headers, new intake, and a new downpipe and I know i cant get what i want out of the mods unless I chip the ECU and reprogam it for better air efficiency so im wondering what Chips out on the market are good, reliable, and actually provide some performance upgrade.

 

oh noes.

I tested "tuning chip" but yeah, it frankly offered bs.....performance chip however worked a lot better.

 

If you think you can handle the horsepower go for it.
