I researched some of the post on here. I have a question. I have a 2010 xl with the 4.6 2 valve engine. I know my truck doesn't make a lot of horsepower compared to the 3 valve, I just don't like the hesitation when you step on it. Which tuner would you recommend? If any at all. Would a cai help any over the stock one? I really like my truck,thanks.

 

I don't think I really have a lot to add but from what I have been reading here 5 star seems to get pretty good feedback. I am thinking about getting their package deal for the 6.2 L. Just have to save up the $$

 

I'd go with VMP tuning. loved their tunes with my 4.6 on my 07.

i've only heard about 5 star for the newer motors, not anything about the olders w/ exception to the 5.4's.

i had a cai on my 07 as well, didn't notice any MPG change or any power what so ever. i could hear the intake which i liked but for $250 i feel there is a better place to spend the money.

 

Thanks for the info, I will check into those.

 

5-star or Vmptuning and they sell the programmers also....
