I just installed a Edge Evolution Programmer like a week ago and when its in power program 2 and 3 it feels like it hesitates or like it studers when driving normal but if i punch it, it takes off good with no hesitation. Any suggestions on why its doing this.










2008 F150 Fx2 Sport 5.4, Edge Evolution Programmer, Roush CAI, Flowmasters Dumped, H.I.D. 8000K, 2/4 Drop

 

Could this be caused because i have a CAI and flows or what could it be.

 

Not an expert but it kinda sounds like the TQ management pgm...turn the readouts to show the TQ control and see if its kivkin in when that happens.

 

The Edge is for stock trucks only. I don't know for sure the Edge is your issue, but it's likely.

You need a Gryphon with custom tunes (http://dygytalworld.ehost-services13...php/Index.html)

 

Ok, I think I know whats going on since my truck was doing the same. Are you going into the tunes, 2 & 3, and changing up stuff, like timing, shift points, rpm, etc? Not talking about rev limiter or speedo. I used to change up the timing, just .25 and my truck would do a "ka chugga chugga" tryin to get right, then just go WAAHHHHH like a bat out of hell. I noticed that changing up stuff like that was too much for the Edge and my truck. I also noticed that if you flashed to STOCK before you go from one tune to the next, it accepts it better sometimes. Good luck (and yea, Get a Gryphon).

 

make sure if ur using level 3 that ur using 91 octane...and dont do a custom tune just put level 3 and use ur 91 octane and ull notice the difference
