First post. I have had an 03 360 spider for 18 months. Considering going F430 spider or upgrading the 360. Any opinions? The 360 mods are software, catbypass, and cap stage 2 exaust. It will definately sound better and said to add 35 hp for about 12K. 25hp from just exhaust and bypass for 8K which I have also considered. Any experiences?
