i added the superchip and holy shart what a difference. the best money i've spent on my truck thus far. i didn't think i could peel out with a 4.6L on 35"s, but i guess it's possible. i had a little help b/c i was on a blacktop, but never the less i could never do that before. also kind of cool it let me recalibrate my speedo. i guess this is what my truck would kind of feel like if i had the 5.4L?

 

Nice man I know how you feel. That chip made a huge difference for my 4.6 as well.

 

Which superchip programmer did you guys get? I have been interested in it but didn't think it would make much difference on the 4.6... maybe I was wrong!

 

superchip model 1815 it's for 98'-08' f150 gas models. go on ebay they're way cheaper on there. and yes it makes a hell of a difference. i couldn't stop flooring it at every light i came too.

 

yea it is a big noticeabke difference, i love mine, i usually run the 87 octane, im gonna run the performance next tank of gas
