You're most welcome. I hope everything works now.

I've experienced the same thing on my truck with the Gryphon. Does it on both the 87 & 93 octane performance tunes. Doesn't do it on the stock tune. Looking forward to seeing if yours got fixed.

I havent used any other tune on my truck but LV3/93 oct. I do not have any other tunes and the only thing my 2008 SCrew 5.4 has is a flowaster 50 Cat Back single side exhaust. EVERYTIME I drive it sounds like I am misfiring, or its not getting enough gas/bad gas. My truck only has 8000 miles on it. Most of the time driving around my town I am under 35mph. I live on Long Island less than 100ft above sea level and rarely have I gone more than 200 feet above sea level. The only time the sputtering stops is when i am getting on it (1/2 throttle or more) or when i really get on it WOT on the highway.

Sometimes I use the throttle position gauge and the majority of the sputtering happens under 15% and at slower speeds. When in stock mode there is a delay in throttle response under 15% so its lose lose - damned if i do damned if i dont. The sputtering doesnt really bother me but the fact that it happens enough that my wife notices it begs me to ask the question/or suggest they have/will a fix for it?

Are we talking the canned tune?
Or a custom tune?
You need to update your user cp too!
With your hex code and programmer serial number.

sent my hex to corey a couple weeks ago, said she was going to send my customs soon - canned tunes no custom yet just level 3 and thats it - ill try the CP but a couple weeks ago i did update pegasus to the newest version - thanks for your reply

Yes if you could put your hex and serial # in your user cp it would be much appreciated!
Also at what rpm is your miss happening at?
Is it more previlant at the begining of a shift?(High rpms) or after the shift?(Low rpms)
Also how many miles on the truck?
Peace!

Its always below 1500, light touch on the pedal to accl away from a stop sign or traffic. I almost feel like its starving for gas or flooding - kinda like the bog you get on a dirtbike thats carb isnt floating right. No issue with shifting - I love what this thing has done to my shifts - honestly besides the great burnouts-quick accel, shifting is my ABSOLUTE Favorite thing about this mod!!!

Hex is in - all updates done - guess I didnt realize I had it set up already - no change in status from above messages.
