My car is an N/A LTD. Eurocharged tuned and dyno'd my car. We got 211.4 RWHP after we did all mods listed in my signiture below. We dyno'd each mod as we did it. They know exactly how much each mod will give. We did stock filters vs. K&Ns, 74mm TB vs. 68mm, 74mm with 3in MAF, elbow debaffled and descreened, etc. and ran dyno runs at each step. They were just like us, they wanted to know. My exhaust is totally stock. Car runs really well, but is no SRT6, but it runs way better than it did stock.
