'10 w/ 4.6 2V

[96grimreaper]

Ok, I know, I know.....new guy with the same old questions.

Before I start making phone calls and sending pm's to several people I thought I'd ask a few questions in a thread first. Also thanks to JackandJanet and 88racing for sending me over here.

I have a 2010 F-150 supercab with the 4.6 2V. Only "performance" mod I have is a si/do exhaust which is really just for sound. I recently put on 295/70/18's and lost a little power. (which I fully expected)

After making multiple phone calls and finding out gears would void my 100k mile powertrain warranty those are not an option, for awhile anyway.

I'm hoping the aid of the Gryphon CS will help me get a little bit back of what I lost.

Now my questions...

Since I do not have any major mods, should I get a custom tune or will the canned tunes suffice?

If I do go with a custom tune will the 87 canned tune be considered the "economy tune"?

Again, if I go with a custom tune I'd opt for the 91, if everyone else thinks the 91 over the 87 would be worth it.

I daily drive the truck approximately 100 miles a day, mostly highway. Truck occasionally tows, and I do go out and play in the mud/sand.

Im just looking towards the experts here for opinions because I've convinced myself I need a tuner. Thank you in advance.
