04.5 wont not rev through the rpms smooth?
My truck seems to run& drive fine. When you free rev it slow up to 3000rpm, it will sound fine, or when you drive it it runs flawlesly lots of power, but if you give it a quick rev up thru the RPMS, it will pop, it sounds like the timming is off, or air/water in fuel, that kindof poping noise. why does it do this? is this a common thing? still very much a newbie to the common rails, and the smarty tunner. It doesnt do it as bad on the lower tune or tunes without the timming added. I have it on level 6 currently. Any help or suggestions?
