I just bought an 08 F150 about 3 months ago and am wondering if anyone has tried a tuner (SCT, Diablo, etc) on one. I was told due to timing issues because they can run 85 octane fuel that you can't use tuners or power adders. Is this true?
I haven't heard anything like that before, I have a Gryphon on my '08 with great results so far. I am running an 87 Octane performance tune and the other tunes installed on the device are also 87 Octane.
I would recommend the Gryphon, and there are a few other guys on this site that also have them, but make your own decision.
First of all..........they cannot run E85 fuel unless it is actually the FFV E85 5.4 engine. If it is it will have a yellow E85 gas cap. My truck is a 2008 but it is not an FFV E85.
Secondly, if it is E85 capable, then you are correct.........a programmer is basically useless at this point.
just under 21 is incredible for a full size truck. who needs an econobox:icon_lol: the best my truck has done is 840 km on the 30 gallon tank once. that was at 100-110 km and the throttlebody spacer and hypertech running 92 octane. made it from terrace BC to watson lake and had been running on LOW FUEL for awhile. had a gerry can for safety.
I just checkd my 08 and it also says E85/Gas....yellow cap as well.....and I was thinking of buying a gryphon.....can someone explian what this E85/Gas means as I dont have my owners manual here.
I just picked up the truck a few weeks ago and I have been running regual unleaded fuel.
from my understanding, it means that you can run gas or E85 or a combination of both. once Bill gets back to me about my tunes i will let everyone know. there shouldn't be a prob writing a gas tune. if you do have to fill up with E85 once in a while.
I get about 750 per tank, if that helps
and my foot is heavy
