All the new ones they make come with the race ECU, so you should get the new one. It's simply a better tweaked fuel/air map so you'll get slightly more hp and tq.

Well i have been doing lots of reading on this subject and from what i have seen there really isn't alot of gains from going with an intake and exhaust as per lets say horsepower but there both more for sound and maybe 1 or 2 extra ponies so i'm not to sure what to do and what to get looking forward to a meet maybe to drive in a car with both and go from there, thanks.......

When it comes to exhaust, there's no real hp gain but you do gain a nice sound. Depending on what u get, the sound can vary from down outright mean to a more subdued growl. As for intakes, not a whole lot in gain there as well. If u really want to make your gs quicker, u have to consider FI, PI, and LSD (stock gear) or PI and 3.76 lsd, or just PI or 3.76 lsd. But keep in mind that by going that route, you will also need to address the stock suspension to better handle the performance gains. Good luck
