Hi all, I can't remeber if I asked this before, so I am sorry if I did.

Questions are

1) I have no problems running the level 3, thats 93 otcaine right? So i should see at least 20+ Hp and 30+TQ over stock?


2) How much extra MPG can I expect? Right now on a 06-F-150 5.4 XLT I am getting 17.5 at 65MPH.

3) I Don't plan on hauling, maybe towing. how much more MPG would a Bed cover net me ?

4) I want to cut the factory muffler off and replace it with something that is louder, but not crazy loud, I was thinking of a 70 series flowmaster or a magna flow, but I don't know much about magna flow.
I also plan on chopping the pip shorter and turning it 90" down, so that the pipe can't be seen.

5) I have regular in it now, if I fill up between 1/4 tank and enpty with 93 would that be ok?

6) I know some one had posted a list of trans shift firm ness, could some one direct me to them?

7) I plan on setting the rev-limiter below the stock of 5,400 would that hurt anything? I just want to play it safe for when I do get on it ( and thats rare my frist truck, and my frist new car/truck )
5,100 would be ok?

Thank you.
