My question is for you experts.
1.Exhaust- yes or no and who makes the best?
2.Air intakes- yes or no who makes the best?
3.ECM-yes or no and i think raptorq is the only one.

So guys before you reply let me tell you what i'm thinking.
I dont want a 8 cyl too much gas. looking for a toad for my rv, and this will be used as my daily driver. I still want something with reasonable power. This is why Im looking for upgrades.
I have my eye on an 06, thinking about putting 35's on it. I know this set up will require a lift, what do you recomend?
1. Rancho 4" lift (smooth ride)?
2. Cranking up keys (very stiff ride)?

So if you can help with any comments I would appreciate it. Thanks in advance

Someone will say it so I guess I'll be first "search" is your friend.
However; I'll do my best to help,
1-exhuast, dont know myself but understand Borla is a good set up(not too noisy)
2-intake, not if you offroad, also basicly a waste anyway no real improvement
3- ecm, did mine w/pcmforless, maybe 1/2mpg better only real difference I noticed was the change in shift firmness the added
As for 35's no lift needed alot on the forum turned thier t-bars(did mine 5 turns to compensate for the extra weight from my winch)ride is about the same as long as you dont go crazy
also according to the discount tire web page calculating speed chande w/tire size changes 33 to 35 is approx 3mph different so your mpg may look worse but my 33's are 3mph slow according to my cop buddies radar.also no way to ajust speedo at this time
keep things off your roof ie. roof racks and your mpg will be ok with my rack on I get 15 to 15.5mpg, off I get about 17mpg
good luck and if you buy get the adv pkg good extras for not that much more
