So far I have deleted the cats (my state does not require so check state epa regs. First) ran dual exhaust, as well. I replaced my throttle body with the 65mm bbk and matched the bbk cai. The next mod I added was the 23lb fuel injectors and a screamindemon coil pack with 10mm wires. Once I got all my mods on i purchased the Bama wireless tuner and synced all my tunes through it. Wow what a difference this has brought this little pony to life.

Here's a link to a video I made about my 2004 V6 autocross project. It details all the mods I made to get more power and throttle response. In addition to the usual bolt-on parts, I installed Harland Sharp 1.8 Roller Rockers, an Auto Specialties Underdrive Pulley, and a RAM Aluminum Flywheel. This car won a local CAM Class autocross championship in 2019.
