    Yeah I remember those days, also when you drilled holes in the throttle blade to get back in the idle circuit with a big cam.

    I didn't mess with the coast or in gear idle stuff, so you may want to play with that a little as you go too. You need to correct fueling via MAF and VE tables. With the cam lope causing an idle change over 50 rpms you'll find a lot of the lean drift will be coming from your VE table as the ecm considers that transient fueling........

    Alot better, timing was adjusted down in ghuggins adjustment , can feel power down a little but everything else seems very close to on point. I'm just gonna have to make time and do ve and maf tuning for sure. Have new gears on the way (4.56) should make a world of difference also.

    Sounds good.

    The idle you had before is what they consider a "forced or ghost like" cam lope whereas the one you have now is more natural

    Def like the natural sound, enuff that anyone knows the engine isnt stock but not enuff that its just plain annoying. Did u by chance take a look at the last tune with the log? I knkw I need both ve and maf tuning but which would benefit me the most to do first? Havent had the time to figure out the steps to take to start the process of wither, have a few motor swaps and 2 trans to change this weekend thru next ( dont get alot done with the 3 hrs after work in my garage when its cold out) but after next weekend I'm gonna make time to get atleast one area of tuning done.
