I have a 2006 5.9 I put a programer on it and the power I got out of it was ridiculous I used to step on the throttle and it would burn the tires off just the other day I couldn't even power break it! It doesn't seem to run bad it just seems like the initial throttle response is not there like it was when I put programer on! Any help would be greatly appreciated !!

 

What programmer? I have the old stupidchip, I have to re-load it once in awhile, and then it is back to full power.

 

. I have the bully dog GT tuner I will try that! I hope it's that easy! How often do you update your programer?

 

Why would even bother with that programer. Upgrade to EFI live.

 

When did EFI for 2005's start? I been waiting and quit watching for it.
