    How does tuning work?

    I will answer you questions: Teh stock computer program has a throttle % rampup that starts the throttle body at ~40% open and allow the throttle body to advance up to 80% over the course of the RPM range. I think by 4000 rpms you are finally at 80% throttle open. The retune changes that to a...

    Nope. Magnuson Moss Act doesn't hold up.

    This may sound dick, but I keep my business cards in my wallet. So back at the lanes you can pull them out and give them your number in case they want some work done on their car to help them catch up to you.

    Let's hope it was dropped in the US. Who really want's to pay $1,000 for a tech inspection after racing?

    That's bologna. The HP restrictions of the past were actually imposed by Japan, and not the US. They had a HP freeze at 276 bhp Up until a few years ago. That's why you RARELY saw a Import with anything bigger than a V6, and also why they loved turbo chargers on their cars so they could produce...

    Big Daddy Cold Air Intake?

    I've never heard of Big Daddy. Untuned CAI's are not AS good as the other ones. Point being......they don't move as much air. The tuner changes WAY more than just the intake. The intake part is only 1 out of the ~30 tables that the tune should alter. You will pick out more power from...

    I still like your picture. I'm posting it on another car forum. I like how it looks like it's in 3D.

    What Mustang Should I Purchase?

    I'll share something with you. When calculating powertrain loss, it is common for most people to quote the % loss, but then incorrectly calculate the inverse to find the crank amount. In order to turn a 20% loss back to 100% you would actually have to add 25% to get back there. 280rwhp at a 20%...

    What's better? Need info.

    More than likely on the race tune he just changed the commanded torque tables to have the car produce more power with less throttle position.

    long tube or short tube - what is the difference?

    Words of advice when tuning the roush. When you put on the smaller pulley I am assuming that you will be hoping for 12psi. The stock AFR from roush can be leaned out to about 11.95, and then the timing can be bumped up to almost match the MBT table. You may also want to raise the maximum...

    Well as Benjamin Franklin said, Someone who is willing to give up a little freedom for security deserves neither freedom nor security. Bush's administration is a full-on circle jerk.

    Amen to side jobs! Are you full-time photographer or part time? I do a great deal of engine tuning on the weekends to pay for my fun times.

    Camaro owners.......

    I drove an LS1 prior to this too. Maybe you guys could learn to drive. Races are fairly even between good drivers in both cars. It's still slightly favoring the LS1. As for the times, yeah those are magazine times. Since the only thing you can REALLY quote is published material otherwise...
