I have a 2004 Steel Grey 5 door 6s (V6). So far I have installed the Injen RD cai and Injen SES catback exhaust. Also have the CP-E Injen fix/maf customizer. I changed my tranny fluid to Redline Mt-90 and in 2k miles I'll be on a full syn oil. Tires are Toyo Proxes 4s. I have CP-E headers on the way in the spring and hope at some point to add the racing beat susp package. After the headers we'll see about a clutch and flywheel. My best wish would be a LSD!
Here is my dyno w/the intake, exhaust and maf add on.
