i have a 04 f150 5.4 3v and i want some more power.. i have the roush offroad exhaust and thats it. i thought about a CAI but ive read that they cause these engines to run lean so,,, i was leaning towards an edge tuner. will the "running lean" problem come into effect once i install this.. keep in mind all i have is the exhaust done. anyone have one that has had problems with it??? i drive 60 miles to work everyday and dont wanna lose any mpgs. tell what ya think thanks!!

 

Please do a search and read as many threads as you can. This has been beat to death!

Kevin, he really doesn't need to do a search, which might be counter productive (unless he can refine a "search" like a Unix guru). He just needs to look through the last month's worth of threads and he'll have his answer!

Absolutely! Go to the Tuner and Programmer's section and start thru the threads.
