Ok guys 05'-06' engine, twin turbos. What else do I need for 500-550hp that is reliable and steady? All the vendors have different opinions and I'm having a tough time weeding through them to get the info I need. I just want steady strong power for street and towing that's reliable. Some reccomend injectors (60HP) who makes the best ones? Fass 150/150? Downloads? Stacked? Thanks in advance for your input!
