    Has anyone done back to back runs on the strip with launch control and without traction control on? I'm going to the drag strip next Friday to hang out but I might run my 15 GT if it's not too busy. I'm still on the stock tires (235s) and I expect traction to be my biggest enemy. I'm...

    Need some machine shop advice!

    I'm working on a project for my truck. I need a custom intake plenum made, but I've requested a few of the local machine shops to give me a quote. I keep getting no-quotes on the job, or they're willing to make partial components. I need some advice on if what I'm asking for is doable, or if...

    Cobra wont stay running

    My cobra is giving me a fit. It's had trouble starting in cold weather before, but not like this. I crank and it will start, and immediately die. Sometimes it will start and try to idle for a few seconds and slowly die. If you give it any throttle, it dies even quicker. Is there any good...

    Datalogging while cranking

    I'm ready to start troubleshooting my 04 F150. I swapped from the 5.4 3v to a 5.4 4v out of an 04 Navigator. The 3v has 2 camshaft sensors, and the 4v of course only has one. I'm not entirely sure how to handle this issue yet. I took a datalog of me trying to crank the truck (less than 10...

    04 F150 5.4 4v Swap

    I'm in the process of swapping a navigator motor into my 04 F150.
