I would highly suggest adding a tuner to your goody list if you have the money. My friend has a 2004 GT and we add a intake, TB, and plenum combo to his car and it picked up some ponies but when we picked up the tuner we definitly noticed a difference in performance. Not to mention he was running way lean although this is at 6000ft above sea level so a/f are really important. When we fixed that we noticed night and day differences from before the tuner and after.
I have heard good things about both brands although if you look at the summit website you can get a Trickflow plenum and 70 mm TB combo for 250. Although it may not have the bling its about almost half the price and you could even settle for a summit brand TB it's basically a Trickflow TB with a summit sticker on the box. There is also C&L plenums. Just do your research and GL on the buy let us know what you end up with.
